Mobile vs. Desktop sizing
I suggest we add something about being consistent in making a distinction between mobile'ish and desktop'ish sizing for template styling, as having items jump around multiple times in an unpredictable matter can be rather annoying. The cutoff point between mobile and tablet/desktop styling for Minerva is currently 720px and 1000px. I suggest we therefore start with these values and ask people to discuss any other media query settings before applying. —TheDJ (talk • contribs) 11:34, 24 May 2018 (UTC)
- Forgive me if I misunderstood, but I read that as saying only media queries with 720px or 1000px would be allowed. I object to this. I have numerous use cases for 320px & 480px breakpoints, which are basically essential for any useful mobile responsivity if there is anything except the simplest layout going on. Additionally it is a cornerstone of modern web design that your mobile and desktop interfaces should share common features and look much the same so as to not annoy or confuse the viewer - but this is best achieved with more breakpoints, not less. Also if someone has designed something that jumps design so dramatically, then that is a problem with that specific design, not the overall system. In short I want there to be flexibility in setting media queries as appropriate to the specific design, or if they must be set, a minimum selection of commonly used viewports. JLJ001 (talk) 17:37, 24 May 2018 (UTC)
- For comparison, the breakpoints in Timeless are – mobile: up to 850px; then desktop-small: up to 1099px; then desktop-mid: up to 1339px; and then desktop-large. - Evad37 [talk] 03:09, 25 May 2018 (UTC)
How about something like this:
- Media queries for screen width should normally use one or more of the following standard values. This limits the number of times content can jump around multiple times in an unpredictable matter.
- 320px (small mobile devices)
- 480px (medium mobile devices)
- 720px (large mobile/tablet devices)
- 1000px (small desktop screens)
- 1400px (large desktop screees)
- Responsive designs should take care to avoid dramatic changes across breakpoints.
- Evad37 [talk] 03:32, 25 May 2018 (UTC)
- Turns out they are actually documented now for Wikimedia:
- 320px (minimum size for a modern mobile device)
- 720px (minimum size for a tablet)
- 1000px (minimum size for desktop screens)
- 1200px (large desktop screen)
- 2000px (extrawide desktop)

- I think that is reasonable. I also think that +- 5px on these breakpoints should be acceptable. JLJ001 (talk) 12:10, 26 May 2018 (UTC)
- @JLJ001: "I also think that +- 5px" What sense does that make, can you clarify ? The whole point of having cutoffs is to not change layout every 5px. —TheDJ (talk • contribs) 20:00, 26 May 2018 (UTC)
- Imagine I wanted to set a breakpoint at 321px for some reason, this is close enough to 320px that it shouldn't be changed if it was done this way. But 326px would be too far off the agreed point and need a good reason to be so. To give an example, I often ( probably wrongly :D ) code min-width and max-width media queries to be 1px separate from each other to avoid an overlap, eg 600px and 601px.

To clarify all these combined plus some I just added is:
- 320px (small mobile devices)
- 480px (medium mobile devices)
- 600px (small phablet devices)
- 720px (large mobile/tablet devices)
- 850px (Timeless breakpoint)
- 1000px (small desktop screens)
- 1100px (Timeless breakpoint)
- 1200px (medium desktop screen)
- 1400px (large desktop screens)
- 2000px (extrawide desktop screens)
- I'm fairly certain there is now a task in the Timeless project to sync the cutoffs to the documented cutoffs. --Izno (talk) 21:18, 27 May 2018 (UTC)
- If that was done we could safely ignore 1100px and 850px, maybe also cut 600px. JLJ001 (talk) 21:22, 27 May 2018 (UTC)

- 'In general, this means it should be a subpage of the related template' In general yes.. but definitely not solely. For instance the main page uses lots of transcluded pages to generate itself. Most likely it will therefor have at least one CSS page of its own, not connected to a template. Haven't looked into that exactly, but it's rather likely. —TheDJ (talk • contribs) 17:09, 22 May 2018 (UTC)

- Are template styles subject to cascading protection? — xaosflux Talk 01:55, 23 May 2018 (UTC)
- Yes, the use of
<templatestyles />
is treated just like a normal template transclusion for things like Special:WhatLinksHere and cascade protection. Note that templates themselves shouldn't be directly cascade-protected though (see WP:PTPROT). Anomie⚔ 12:03, 23 May 2018 (UTC)- @Anomie: thanks - validated with a protection demo here: testwiki:Template:NTMP1/styles.css. — xaosflux Talk 12:51, 23 May 2018 (UTC)

- I have created Template:Styles import. The idea is that putting {{Styles import}} on the page will add a standardised link to the stylesheet, and warn if it doesn't exist, giving a link to create it. If this was used universally it would ensure all the TemplateStyles usage was uniform, and help cut down mistakes. What do you think? JLJ001 (talk) 11:50, 26 May 2018 (UTC)
- Note such a template is not necessary to display a message if the target stylesheet doesn't exist. TemplateStyles will already display a message something like Page Template:Example/style.css has no content. if the named page does not exist (taken from MediaWiki:templatestyles-bad-src-missing). It also has messages for if the "src" parameter is omitted, if it's an invalid title, and if it's not the right content model (e.g. if you try to use a wikitext page as CSS). Anomie⚔ 16:20, 26 May 2018 (UTC)
- I didn't realise that, that's enormously useful. looks like error checking is built in. While I am thinking about it, is it possible to list all pages using TemplateStyles / all pages with TemplateStyles errors? JLJ001 (talk) 16:38, 26 May 2018 (UTC)
- You can find all style pages (i.e. pages with the TemplateStyles "sanitized CSS" content model) by searching for
contentmodel:sanitized-css
from Special:Search (e.g. [1]). You can find all pages using a particular style page using Special:WhatLinksHere, just as you can find transclusion of a particular template that way. There's no straightforward method that I know of to find pages with these errors or to find all pages using any TemplateStyles CSS page. The latter seems rather unlikely to be implemented, but a tracking category for pages with errors could be added easily enough (file a request for one in Phabricator, being sure to tag it with TemplateStyles). Anomie⚔ 17:54, 26 May 2018 (UTC)- Ok thanks. I am not feeling evil enough to throw extra work at the people implementing this at the moment, but it's nice to know that it's an option if needed. JLJ001 (talk) 18:18, 26 May 2018 (UTC)
- There's no harm in requesting it. If the developers don't think it's important enough to make time to do it, they'll just leave it in a backlog. BTW, there's also the fact that one of the two people likely to implement it is me with my other hat on. ;) Anomie⚔ 20:50, 26 May 2018 (UTC)

Citation templates
Could some TemplateStyles expert comment on Help_talk:Citation_Style_1#Arbitrary_break, and at least tell us if styling citation templates with TemplateStyles would be possible? Headbomb {t · c · p · b} 00:58, 6 July 2018 (UTC)
- That seems a bit iffy. It might be possible, but might require some excessively weird HTML. TemplateStyles is enabled on testwiki if you want to try things there, or you could try using your common.css here to test things out (being aware of certain CSS features that aren't supported in TemplateStyles, such as CSS variables). Anomie⚔ 13:14, 6 July 2018 (UTC)
- @Headbomb: I think it would be quite unwieldy to do it with TemplateStyles (if you were to do it by adding a parameter to {{Reflist}}), since you would probably have to have HTML classes hardcoded into every name (e.g.
<span class="name"><span class="first"><span class="initial">W</span>illiam</span> <span class="last"><span class="initial">S</span>hakespeare</span></span>
) and you would also have to have them such that you could show the text in the orders needed; you'd basically be addingdisplay: none
to all of the superfluous text. You would also not be able to affect citations not based on the CS1 module. Using Lua inside the cite templates seems far more manageable and should be implementable as you proposed, although the module would have to be able to handle cases like hyphenated names. - @Anomie: Please correct me if I'm wrong about this.

How do I edit sanitized-css stylesheets?
I've made a version of the {{clade}} template to use TemplateStyles, using the {{cladeN}} template. It mostly went smoothly with testing using my custom.css. I copied the working css to a style subpage {{cladeN/styles.css}} before templatestyles was enabled earlier today. This more or less worked as expected. However, since TemplateStyles was enabled I can't edit the style sheet further. The message is You cannot edit this revision because its content model is sanitized-css, which differs from the current content model of the page wikitext
. I assume this is a privileges issue, but it gives no further information. Jts1882 | talk 16:30, 19 July 2018 (UTC)
- This might be Special:ChangeContentModel but I don't know what to change it to. Clearly the default syntax highlighting doesn't recognise sanitised CSS. --Redrose64 🌹 (talk) 20:00, 19 July 2018 (UTC)
- According to WP:TSTYLE#Tips, they use the
sanitized-css
content model. Since the page was created before the TemplateStyles extension was enabled, it was created aswikitext
content model, so an admin would need to change it. See also: mw:Content handlers. — AfroThundr (u · t · c) 22:39, 19 July 2018 (UTC)- I fixed it for you. Apparently MediaWiki gets a bit confused if the default content model of a page changes, I had to change it to something else then back to Sanitized CSS. I think some upcoming work for multi-content revisions will fix that behavior, eventually. Anomie⚔ 00:58, 20 July 2018 (UTC)
- According to WP:TSTYLE#Tips, they use the
Tree list
FYI, I recently converted {{Tree list}} and was able to remove it's styling from MediaWiki:common.css, as well as making two of its' subtemplates: {{Tree list/final branch}} and {{Tree list/final branching}} unnecessary. Progress baby... —TheDJ (talk • contribs) 08:21, 26 July 2018 (UTC)
A simple test case: Talk quote inline
I've made a simple test conversion of Template:Talk quote inline (aka {{tq}}). I have a thought or two--maybe someone will disagree.
We should probably use semantic naming for our classes where possible. "talk", "talk2", and "talk3" are not very semantic. Which leads to a question: What should one do when there are already existing classes, not named well, which might be used by various and sundry people to style this template already (basically, what to do with old class names)? I would prefer not to retain, or even leave for deprecation in any significant period for a simple template such as this one, the old class name. I'd also not like to have to bug an (technical) administrator to make the changes for me.
A second question: In the above case, I have all of the styles in one sheet. Some however will not be used in a single invocation (italic and sans-serif, in particular). Does that mean that there should be more than one styles page? It seems from the above discussion I can invoke as many templatestyles invocations as I please (and maybe I might please to put them inside the conditional expressions... is that verboten? :). Or, if the particular class doesn't appear on the page, I've now shipped some CSS not needed for that page (which is minimal, but it would not have happened prior even though every infovocation in the end-HTML would have gotten it, so that of course would be larger than the CSS). Thoughts appreciated. (Maybe these are cached on the user side and it's mostly a non-issue?) --Izno (talk) 22:53, 25 July 2018 (UTC)
- On the first question, I'd be very much in favour of semantic names for the classes, such as
inline-quote-italic
instead ofinline-quote-talk2
, etc. I'm pretty sure that I'd simply replace the previous names with better names in the template and its TemplateStyles stylesheet if existing class names are poor. Then the older names would simply be unused and somebody would eventually remove them from common.css (if that's where they are). The only chance of affecting anybody else is if they use the old class names in their user css to provide overrides. I guess an insource search for definitions of the old class names within userspace should turn up any. Then it would be just a matter of leaving a note to the user that they need to update their user.css. --RexxS (talk) 00:16, 26 July 2018 (UTC)- A non-specific followup: should the template emit both a talk-quote-inline and a talk-quote-italic? So someone can target the whole template? --Izno (talk) 00:57, 26 July 2018 (UTC)
- That would make sense if you wanted users to be able to target the entire thing with their own CSS. There isn't any specific reason I can think of why you couldn't just add the class even if you weren't currently using it. If the names are unique (properly namespaced) the extra class wouldn't affect anything. — AfroThundr (u · t · c) 04:54, 26 July 2018 (UTC)
- A non-specific followup: should the template emit both a talk-quote-inline and a talk-quote-italic? So someone can target the whole template? --Izno (talk) 00:57, 26 July 2018 (UTC)
- Please, also remember that bots (on wmflabs) and scrapers might have expectations with regard to the presence of certain classes. So i'd take significantly extra care with templates that are part of processes etc. —TheDJ (talk • contribs) 08:28, 26 July 2018 (UTC)
Idiot's question: substing
What happens when I subst a template with a template style invocation? None of the docs pages I looked at indicated that anything different should happen (all were silent on the matter, in fact), in which case I would expect the template style sheet tag to be added to the page on which the template is being substituted.
Is that the case? --Izno (talk) 15:45, 25 July 2018 (UTC)
- @Izno: Here's what I get when I
{{subst:thermometer}}
:
- The source of the styles is still there in the
<templatestyles />
tag. The thermometer renders correctly, so the styles are applied. That can be checked by using the browser inspector. --RexxS (talk) 15:56, 25 July 2018 (UTC)- Should templates with template styles be substed? If a different question: should templates meant to be substed use template styles? Do the styles load once with each invocation or once per page when there are multiple tags pointing to one place? --Izno (talk) 16:06, 25 July 2018 (UTC)
The problem with all of this is that the classes "leak out" onto the page, which means we need to pick unique class names, otherwise we can get all sorts of unexpected interactions. --RexxS (talk) 16:10, 25 July 2018 (UTC) | Text inside a div The div has a class name matching one used in a TemplateStyles tag on the page.

- It doesn't make any difference as far as I can see. The classes will be available to the rest of the page content whether we subst or not. I would expect each invocation to call the stylesheet, as I can't see any reason why it wouldn't. Should be easy enough to test. --RexxS (talk) 16:10, 25 July 2018 (UTC)
- First calling {{Thermometer/sandbox1}}: The sandbox version has blue fill, and because it uses the same class names, it overrides the red in the original.
- Then calling {{Thermometer}}: Contrary to my expectation, calling the original template once more does not restore the red colour. I infer then that subsequent template invocations do not reload the original style sheet. You can confirm that

– once per page, per mw:Help:TemplateStyles#In_which_order_do_CSS_styles_override?we need to pick unique class names, otherwise we can get all sorts of unexpected interactions
– yes, hence the third bullet point of these guidelines. - Evad37 [talk] 16:31, 25 July 2018 (UTC)- There is a stray blue thermometer bulb on the page.
- The example is calling two different templates, each inserting an inline stylesheet. Calling the red one again doesn't restore the red as it uses the earlier inline style and the sandbox style with the blue is later in the page.
- It does demonstrate the importance of unique class names. Jts1882 | talk 16:44, 25 July 2018 (UTC)
- The "stray" bulb is deliberate (I've just made that clearer). It demonstrates what happens when you use a class name on a div that is the same as one used in a templatestyles stylesheet.
"Calling the red one again doesn't restore the red as it uses the earlier inline style and the sandbox style with the blue is later in the page."
There are no inline styles here. If you subst the templates you get exactly the same effect. That would show that even though the second call to Template:Thermometer/styles.css (red) is later in the page than the first call to Template:Thermometer/sandbox1/styles.css (blue), the software does not load the first (red) stylesheet again, as you might expect that it would for cascading style sheets.

It is imperative that class names are chosen to be unique to a template, as the above demonstrates. Do you think that we can make any improvements to the guidelines to reinforce those points? --RexxS (talk) 20:29, 25 July 2018 (UTC)

GoodWe probably should avoid having substed templates litter the wikitext with
I wonder how often this happens. I know there are a few templates which set "this template must be substed" and then a bot goes around and substs them (that's yours!). And, I wonder how many times these templates have styling. Let's see if we can find that out before we ban template styles in substed templates?

But, most subst-only things are talk page templates I think with a few templates like the German infoboxes scattered around (and we obviously wouldn't add template styles to those templates because we prefer our templates).

Another point comes to light. Because a /sandbox page shares the documentation with the main template, you can't use {{Uses TemplateStyles}} to point to a different "sandbox" version of the stylesheet for testing changes to the stylesheet. To avoid confusion, I've now shifted to Template:Thermometer/sandbox1, Template:Thermometer/sandbox1/styles.css and Template:Thermometer/sandbox1/doc to use when testing changes to the styles. --RexxS (talk) 20:55, 25 July 2018 (UTC)

- I think the latter is neither reasonable nor fine for testing changes to styles. The documentation for Template:Example/sandbox will state that it's using Template:Example/styles.css, but it won't. It will be using Template:Example/sandbox/styles.css if you want to test changes to styles. What's the point in having documentation that's wrong? Just use sandbox1 and the problem goes away. --RexxS (talk) 23:48, 25 July 2018 (UTC)

- Get the name of the template css pages in the module and insert a /sandbox/, then provide that in the use templatestyles box? IMO it would be preferable either way to link these things at the bottom of {{documentation}} with all the other standard subpages.

It will be using Template:Example/sandbox/styles.css if you want to test changes to styles. What's the point in having documentation that's wrong? Just use sandbox1 and the problem goes away. --RexxS (talk) 23:48, 25 July 2018 (UTC)
- {{Uses TemplateStyles}} just adds a normal wikitext link to the styles... it doesn't stop you using a sandbox version of the styles in the template's sandbox. - Evad37 [talk] 01:10, 26 July 2018 (UTC)
- The real problem is that testcases for changes to styles will have to be on separate pages. - Evad37 [talk] 01:13, 26 July 2018 (UTC)

- @Evad37: I don't know how many times I have to explain this, but the /sandbox uses the documentation page for the main template, not a separate one. You only get to use {{Uses TemplateStyles}} once for both templates. So which .../styles.css do you target in {{Uses TemplateStyles}}? the one for the main template or the one for the sandbox? Whichever one you pick, it will be right for one of those templates and wrong for the other. --RexxS (talk) 10:44, 26 July 2018 (UTC)

- Sorry I misunderstand before. I've changed {{Uses TemplateStyles}} so that if the sandbox version exists (as a subpage of
/sandbox/
), it will be included in brackets after the main link. See the box above the documentation at Template:Uses TemplateStyles for an example. - Evad37 [talk] 17:06, 26 July 2018 (UTC) - The other thing you could do is have some page name logic for the page transcluding the doc, e.g. with {{when on basepage}} - Evad37 [talk]

@RexxS, TheDJ, Evad37, and Izno: Should text like "Do not use TemplateStyles in a template that should be substituted; in templates with TemplateStyles, use Module:Unsubst or Module:Unsubst-infobox to prevent accidental substitution" be added to the guideline? Jc86035 (talk) 10:54, 26 July 2018 (UTC)

TemplateStyles in Modules
Hello. I am trying to add templateStyles CSS in a module I am working on in the sandbox (Module:Sandbox/Ita140188/chart2). Is there any way to test the module with a sanitized-CSS without creating subpages of Template:Template sandbox or similar? I tried with User:Ita140188/sandbox/styles.css but of course it would not work ("Page User:Ita140188/sandbox/styles.css must have content model "Sanitized CSS" for TemplateStyles (current model is "CSS")."). Is there a way to make an exception for specific pages? Thank you. --Ita140188 (talk) 05:36, 30 July 2018 (UTC)
- An admin can set the content model for a particular page. I don't know whether there would be any further problems. Please post the final result here. Johnuniq (talk) 05:53, 30 July 2018 (UTC)

In the context of meta templates
Right now Template:Infobox, Template:Navbox, and Template:Sidebar all allow custom styles (usually with multiple parameters). What approach should we take for template styles here?
My inclination is to add a parameter to each (|template style=
or similar using frame:extensionTag
) with the name of the TemplateStyles page. This would also allow us to track those templates where |style=
is still used for conversion. Such a parameter would also allow us to track color combinations for accessibility.
The immediate alternative is that we just use a normal invocation on each template page, but I'm not really in favor of that one.
Thoughts? --Izno (talk) 01:35, 27 July 2018 (UTC)

Sandbox naming convention
What should the sandbox version of a TemplateStyles page be named? This affects the way Module:Uses TemplateStyles looks for such a sandbox page.
- Template:Example/styles.css and Template:Example/sandbox/styles.css, which came up in discussion § Idiot's question: substing above
- Template:Example/styles.css and Template:Example/styles.css/sandbox, which is what this change to the module would suggest
- Template:Example/styles.css and Template:Example/styles.css/sandbox.css – similar to above, but would allow for creation with sanitized-css content model for non-admins
Or something else? - Evad37 [talk] 01:55, 30 July 2018 (UTC)
- Template:Example/styles.css/sandbox seems best to me, for consistency with all other sandboxes of subpages, which follow the name pattern "Template:foo/subpagename/sandbox", not Template:foo/sandbox/subpagename". Inability to create directly isn't a problem; non-admins can just do what I did with a move. {{3x|p}}ery (talk) 02:05, 30 July 2018 (UTC)

- Having CSS pages not deviate from the standard CSS pages naming convention, as described in mw:Help:TemplateStyles #Usage, seems like a good reason to have pages that end in ".css". I'm unconvinced that a sandbox page has to end in "sandbox". --RexxS (talk) 08:18, 30 July 2018 (UTC)
- There is indeed more than one possibility, determined by context. Consider these two questions: (i) what is it a sandbox of? (ii) what is this stylesheet intended to affect? Imagine we have an existing template, Template:Example; that template has a stylesheet at Template:Example/styles.css but it also has a sandbox, Template:Example/sandbox. The page that we are trying to decide a name for might be the sandbox for Template:Example/styles.css which would make its name Template:Example/styles.css/sandbox. Or, the page might contain the stylesheet for Template:Example/sandbox which would make its name Template:Example/sandbox/styles.css. So it comes down to: what are we intending to demonstrate/test. --Redrose64 🌹 (talk) 08:39, 30 July 2018 (UTC)
- I'll have to disagree with the possibility of two contexts. A sandbox for Template:Example/styles.css is unusable per se, because Template:Example does not point to it. Any sandbox version of Template:Example/styles.css is necessarily also the stylesheet for Template:Example/sandbox, which would be the template that points to it. Template:Example/sandbox/styles.css seems the right choice to me. --RexxS (talk) 09:07, 30 July 2018 (UTC)
- By the same fallacious argument, a sandbox for {{db-multiple/item}} is unusable because {{db-multiple}} does not point to it. But that clearly isn't true -- I even personally used that sandbox for a deduplication of the code of {{db-multiple}}. Again, I'm failing to see why TemplateStyles CSS is special here. Presumably, {{db-multiple/item/sandbox}} could also be interpreted as the /item subpage of {{db-multiple/sandbox}}, creating the same dicontextual dilemma. But yet the /sandbox part has found itself at the end, so the same convention should apply to TemplateStyles CSS {{3x|p}}ery (talk) 13:59, 30 July 2018 (UTC)
- There's nothing fallacious about the argument. Your analogy is faulty because the template Template:Db-multiple/sandbox calls Template:Db-multiple/item/sandbox, which is where you tested your changes (and could view the results in Template:Db-multiple/sandbox). Unless you create a template to see the effects of changes to a stylesheet, you can't test the changes.
- The template Template:Example contains a tag
<templatestyles src="Example/styles.css"/>
, which "pairs together" the template and its associated stylesheet. If you want to test changes to the stylesheet in a stylesheet-sandbox, you need a corresponding template that is paired with the stylesheet-sandbox, because the changes won't show up in Template:Example. In what template are you going to put the modified <templatestyles /> tag that links to the stylesheet-sandbox? - There is no "second context" where you can test the effects of changes to a stylesheet-sandbox without having a paired template-sandbox to display the effects.
- Templates and stylesheets go in linked pairs, so it's obvious that we would use Template:Example/sandbox and its associated stylesheet Template:Example/sandbox/styles.css.
- There is no obvious template that should pair with Template:Example/styles.css/sandbox, which is why it's a poor choice of name. --RexxS (talk) 14:34, 30 July 2018 (UTC)
- On purely technical grounds, I wouldn't like .../styles.css/sandbox because of the content model issue, and I have no idea why anyone should have to go around the issue since this isn't reader facing. Stylesheet sandboxes can be tested in tandem with the template sandbox or with the user's web browser's inspector utility. .../sandbox/styles.css makes more sense to me than .../styles.css/sandbox.css because in order to test this hypothetical TemplateStyles sandbox the sandbox template would have to be used. Personally, for {{Routemap}} I used a copy on the German Wikipedia as the sandbox before TemplateStyles was enabled here. Jc86035 (talk) 15:24, 30 July 2018 (UTC)
- That just makes no sense. TemplateStyles is not special here in any way that I'm understanding -- there's no technichal reason why the MediaWiki developers couldn't have coded it so that instead of typing
<templatestyles src="Foo.css" />
to add a CSS page, you could just add them like you do regular templates, as{{foo.css}}
(note: I'm not endorsing this hypothetical as it would be confusing, just presenting it for the sake of argument), which would make it literally the same as my {{db-multiple/item}} case above. - Let's take another example of a non-standard type of page: module
/data
s. All of your arguments seem to apply there:- Module:Good article topics (arbitrarily chosen) includes
mw.loadData("Module:Good article topics/data")
which "pairs together" that module and its data page. Testing changes to the /data page requires a corresponding paired module. - There is no "second context" where you can test the effects of change to a datapage-sandbox without having a paired module-sandbox to
mw.loadData
it. - Modules and datapages go in linked pairs, so according to you it's obvious that we would use Module:Good article topics/sandbox/data
- There is no more reason for Module:Good article topics/sandbox to go with Module:Good article topics/data/sandbox than there is for Template:Example/sandbox to go with Template:Example/styles.css/sandbox
- Module:Good article topics (arbitrarily chosen) includes
- and yet, despite all of this, Module:Good article topics/data/sandbox is not called Module:Good article topics/sandbox/data, as it should be. TemplateStyles should be exactly the same. {{3x|p}}ery (talk) 20:38, 30 July 2018 (UTC)
- Good. So we agree then that when a template and its stylesheet are paired, testing changes to the stylesheet requires a pair of sandboxes: a template-sandbox and a stylesheet-sandbox. You agree then that you can't have a stylesheet-sandbox without having a template-sandbox. We agree so far. That means that Redroses's two possibilities reduce to one, because the sandbox of the stylesheet is indistinguishable from the stylesheet of the sandbox. Have you accepted that yet?
- There is no doubt that the template is named Template:Example and its template-sandbox is named Template:Example/sandbox.
- There is no doubt that the stylesheet is named Template:Example/styles.css. I assume all of that is common ground.
- Now that we've agreed there are not two different possibilities for the stylesheet-sandbox/sandbox-stylesheet because they are necessarily the same thing, that returns us to the original question: how to choose between Template:Example/styles.css/sandbox and Template:Example/sandbox/styles.css?
- In favour of Template:Example/sandbox/styles.css are that:
- we seem to append "/styles.css" to any template to create its stylesheet.
- there are recommendations at mw:Help:TemplateStyles #How does it work? that state
"The recommended usage pattern is to store the styles for Template:Foo under a subpage like Template:Foo/styles.css"
and at Wikipedia:TemplateStyles that state"In general, this means that a style page should be a subpage of the related template"
. - creating pages that end in ".css" fits with the requirement at mw:Help:TemplateStyles #How does it work? that stylesheet pages
"must have the sanitized-css (Sanitized CSS) content model, which is the default for subpages in the Template namespace that end with .css"
and technical advantage that we automatically get a sanitized-css page if we end it in ".css".
- In favour of Template:Example/styles.css/sandbox is that we normally append "/sandbox" to a template to create a sandbox for testing. However, I'm not aware of any documentation that indicates that, nor any technical advantage in using that scheme.
- Have I missed anything out of that summary? --RexxS (talk) 22:17, 30 July 2018 (UTC)
- We do seem to be agreeing over the facts, but not over the reasons. The whole "styles of sandbox vs. sandbox of stylesheet" business also applies to module data pages, where it is debunked by actual practice, and therefore holds no water. Next comes the guidelines, which I think you're misinterpreting/applying too strictly, as it is a (future/experimental) stylesheet for Template:Example, which it is a subpage of. The only argument left after that is the technichal one about contentmodel, which I have no refutation for but think is trumped by standard naming conventions (which you disagree with) and in any case leaves the "/sandbox.css" option open. {{3x|p}}ery (talk) 22:39, 30 July 2018 (UTC)

Experiment with article-space: tables
I recently created Template:American Open Wheel driver results legend/styles.css for Template:American Open Wheel driver results legend. The way I structured the CSS, it also allowed me to make this edit. Who feels good/bad with this? Should we generally enable this kind of replacement for tables with legends (or tables generally)? (I note the existence of phab:T176272 for this particular question.) --Izno (talk) 18:16, 5 August 2018 (UTC)

- I wonder if that's a serious or a rhetorical question--if the former, in the styles.css page for the legend. --Izno (talk) 19:04, 5 August 2018 (UTC)
- That has selectors like
table.aow-driver-results tr td.gold
- why was it not possible to usetable.aow-driver-results tr td.aow-gold
etc.? See Wikipedia:TemplateStyles#Guidelines third bullet. --Redrose64 🌹 (talk) 19:12, 5 August 2018 (UTC)- The first selector "table.aow-driver-results" makes the latter selector "td.gold" only apply within the specific table, so doing that is unnecessary. (this is basically doing "use .myTemplate tr rather than tr") Galobtter (pingó mió) 19:25, 5 August 2018 (UTC)
- Not per se unnecessary, just unlikely that I would have a collision with another template so long as the CSS related to the gold or silver class in the other template also takes good practice into account (i.e., .mytemplate-gold for any old class or table.mytemplate tr td.gold for another table, etc.). --Izno (talk) 19:51, 5 August 2018 (UTC)
- (edit conflict) @Izno: It looks like a perfectly good use of the functionality to me, even if it was not intended by the developers. Obviously you have to have the templatestyles tag somewhere on the page, but I assume that the table will always co-exist with the legend template, so that is taken care of. Should the functionality of the tag be constrained to its template at some point in the future (i.e. no "leakage" onto the rest of the page), then you could create a template to hold both the table and the legend and apply templatestyles to that. I see no downside to what you've done.
- @Redrose64: Since the classes "gold", "silver", etc. are selected only when inside a table whose class is set to aow-driver-results, I think that satisfies the reasoning behind
"Use selectors and class names that are highly likely to be unique to the style page."
There's certainly no problem with using the longer classnames for the table cells that you suggest, but I don't think it would yield any increase in specificity in practice. The shorter names would be more intuitive for other editors to pick up and use, so there is some advantage in using Izno's convention. --RexxS (talk) 19:32, 5 August 2018 (UTC)- Indeed. --Izno (talk) 19:51, 5 August 2018 (UTC)

- Does the response here mean the following bullet is still consensus?
The style must apply only to the associated template's output. It would be confusing if adding a template to one part of a page were to completely or partially change the display or styling of an unrelated part of the page.
- --Izno (talk) 16:17, 13 August 2018 (UTC)
- I think in general, yes – e.g. adding a template in the middle of an article shouldn't affect how unrelated sections (e.g. the references at the bottom) are styled. Guidelines do allow for occasional, common sense exceptions, which I think would include a template that builds part of a table applying styles to the whole table, as might also be the case for foo-start and foo-end templates styling the wikitext in-between them. - Evad37 [talk] 02:04, 14 August 2018 (UTC)
Something needs to be done about this stylesheet: it's misused across like ten or so different templates as a generic means of implementing blinking text. {{3x|p}}ery (talk) 22:59, 4 March 2019 (UTC)
- @Pppery: like what? And why is this an issue? Looks to all be userspace stuff. — xaosflux Talk 23:33, 4 March 2019 (UTC)
- There's very few transclusions outside of User and User_talk namespaces, where it seems to generally be used for a single blinking character in userboxes like Template:User OS:Dos. Perhaps it should just have a tracking category for usage outside of these namespaces in a css comment. - Evad37 [talk] 23:41, 4 March 2019 (UTC)

I recommend, if no one else comments, creating a {{blinking cursor}} and converting all the uses for a blinking cursor to that template, while removing the blinking from any templates that use it for something other than a cursor. Template:Statustop is one example of the latter. @Izno, Evad37, and Xaosflux: Any comments? {{3x|p}}ery (talk) 04:14, 5 March 2019 (UTC)

Issue with style being applied to other, unrelated code
I have an issue. In Template:Awards table5/styles/sandbox.css I was trying to make the text in the last column be centered, but a user reported that the style is leaking to other tables on the page. I then used edited Template:Awards table5/styles.css to use ".awards-table-5", but that just made the code not work anymore. Any idea on how to make it work and not leak? --Gonnym (talk) 09:49, 12 August 2019 (UTC)
- Shouldn't it be "table.awards-table-5"? Jts1882 | talk 10:20, 12 August 2019 (UTC)
- Rather, you could just get rid of
table
. However, this will not always work.td:last-child
will always select the lasttd
element in every row, so if the table contains a combined ref cell (withrowspan
), the style can spill over to other columns. But since {{won}}/{{nom}}/etc are centered anyway, one way to prevent it is to never userowspan
for a cell in the Results column (which is the recommended way anyway). Nardog (talk) 10:54, 12 August 2019 (UTC)- Thank you both. --Gonnym (talk) 11:40, 12 August 2019 (UTC)
- For anyone reading this later, the trick to making ".awards-table-5" work was adding that class to the template as in Special:Diff/910479092 or Special:Diff/910483702. Anomie⚔ 11:44, 12 August 2019 (UTC)

Substed templates r2
So, I did some hunting/poking. For templates which are regularly substed, we can make it so the templatestyles tag is not substed along with the rest of the template. This came up in the context of Template talk:Allcaps where I noted a solution like Template:Smallcaps would work.
I'd like to change the guidance accordingly.
The one question I have is whether, when substing, we should output an inline-styled version (as in that version) or a style-less version. My preference is for the style-less version. Opinions are welcome. --Izno (talk) 17:48, 8 October 2019 (UTC)

Solved. Need help with multiple templated tables on the same page using the same styles.css
Quantocius Quantotius provided some wikitext to add a collapse button to all the 3 partially closed tables at the top of this article:
- COVID-19 pandemic by country and territory - in the "Statistics" section.
Wikitext for "Show all" button:
<div class="covid-show-table" style="font-size:80%;font-weight:500;">[[#covid19-container|[show all]]]</div>
Wikitext for "Collapse" button:
<div class="covid-collapse-table" style="font-size:80%;font-weight:500;float: right;">[[#top|[collapse]]]</div>
The 3 table templates:
- Template:COVID-19 pandemic data
- Template:COVID-19 pandemic death rates
- Template:Monthly cumulative COVID-19 death totals by country
The "Show all" and "Collapse" buttons work on the separate template pages.
But the buttons only work on whatever is the top table in the article itself. If I click "Show all" on the bottom 2 tables they only open up the top table. The collapse button only shows up on the top table. |
Any ideas? Any help would be appreciated. Here is the TemplateStyles css page:

How to do "/doc" template styles?
TL;DR: What is best practice for {{documentation}} of a TemplateStyles css subpage?
Long: It's in templatespace ;-) I noted, one cannot & doesnot add the habitual "<noinclude>{{documentation}}</noinclude>"
to a .css page. All fine.
OTOH, I'd like to work with these css pages, off css-coding. Think background categorising, track usage, planning standardisation.
-DePiep (talk) 22:43, 20 February 2021 (UTC)
- For sufficiently 'longterm' comments, the styles page itself is fine. For shortterm comments, use the talk page of the primary template as is normal for coordination. --Izno (talk) 22:50, 20 February 2021 (UTC)
- Not just comments, I meant. More like automate, categorise. Categorise by talkpage you mean? The horror; see also this GA talk scroll #bottom cats.

- Anything but categories can and should be placed on the main template’s documentation subpage. Categories may not be applicable there; if they are really useful, they can be included as CSS comments (
/* [[Category:Foo]] */
), and they will appear at the bottom of the page. —Tacsipacsi (talk) 00:52, 21 February 2021 (UTC)- Do you have a live example of

? Would be great. -DePiep (talk) 00:57, 21 February 2021 (UTC)- I don’t have one at hand, but you can just edit a TemplateStyles page and click preview. While searching for a test page, I found Template:MongolUnicode/fonts.css, which includes {{pp-template}} (rather than a literal category) in the same manner, and it works. However, I don’t know what performance implications these categories/templates have (one of template documentation subpages’ purposes is to improve wikitext processing performance), so I’d use this technique very cautiously and rarely. —Tacsipacsi (talk) 01:06, 21 February 2021 (UTC)

HTML 5 compliance issues relating to TemplateStyles

The second would seem fixable by giving it an itemprop

- The use of the style/link tags and why TemplateStyles are injected as inline as they are is documented in phab:T155813. It does not look like HTML validation was chief among the decision criteria in so far as it doesn't seem to have been considered at all. Obviously browsers don't mind loading the CSS for <style> wherever it is found in the page. I am not sure if it is worth it to add a Phab task for this, at least as documentation that the use of TemplateStyles will cause HTML validation to fail, or e.g. better to put something in mw:Extension:TemplateStyles as a warning to users. Or both.
- I don't see itemprop mentioned in Phabricator for the design of TemplateStyles, so that may be something that can be fixed. Recommend a phab task for this regardless of the other. --Izno (talk) 22:18, 20 December 2020 (UTC)
- Its not valid html5 and a known issue, but it falls within the parsing rules for foreign/invalid content and all browsers support it (because of shadowcontent, webcomponents and scoped css legacy). It's part of the "we are not valid for validness sake, but for actual valid results"-policy (similar to how we used to include 'invalid' IE specific stuff to make certain things work in IE). —TheDJ (talk • contribs) 20:19, 22 December 2020 (UTC)
- btw. this might change at some point when we fully switch to Parsoid, as it is easier to postprocess HTML with Parsoid to correct something like this. —TheDJ (talk • contribs) 20:25, 22 December 2020 (UTC)
It's part of the "we are not valid for validness sake, but for actual valid results"-policy
Right, I left that unspoken, and apparently so did the RFC participants. That's why I am not sure whether it should be a Phab task or a note on the extension page. You say it's a 'known' issue but I see no evidence of it being known. ;) (I am fully supportive of TemplateStyles, just casting some doubt on the documentation, which is nothing new for most software projects ;).) --Izno (talk) 21:06, 22 December 2020 (UTC)
Maximum tool compatibility
For maximal compatibility with browsers and other tools, it would be best if this emitted <link rel="..." />
instead of <link rel="..."/>
. While the space is not required in HTML 5, it is in XHTML and is also expected by various parsing tools (even some of our own internal ones like the syntax highlighter gadget will barf on <br/>
, and mis-highlight the entire page after that point, which doesn't happen with <br />
). — SMcCandlish ☏ ¢ 😼 04:08, 15 December 2020 (UTC)
- @SMcCandlish: Is it really invalid in XHTML, not only in HTML4? As far as I remember, XHTML (XML) doesn’t require spaces before self-closing slashes, it’s just a custom in order to prevent old HTML4 parsers from failing on this. But HTML4 is long dead, so probably we can go without supporting it. Anyways, TemplateStyles uses MediaWiki core’s Html::rawElement indirectly, which can, of course, be changed, but this change may (or may not) have larger impact by adding a lots of bytes to page HTMLs. Feel free to open a Phabricator ticket about this if you think it’s really important (and find no existing ticket about it). —Tacsipacsi (talk) 14:39, 22 December 2020 (UTC)
- Correct, it is not invalid XHTML. The space is indeed traditional to help HTML 4 parsers from when XHTML was initially developed (15 years ago now). Modern web browsers have no issue parsing either version these days, most older web browsers have no issue parsing either version, and I expect most web spiders are operating as expected as well. Even systems like Notepad++ have no issue with either version. --Izno (talk) 19:58, 22 December 2020 (UTC)
- MediaWiki outputs HTML 5 as identified by the doctype at the beginning of each HTML page. Not HTML 4 and not XHTML (1, 2, or its HTML 5 flavor, which is given barely-passing mention in the specification). Anyone parsing anything that is output by MediaWiki with another model is wrong or is choosing to do something dumb at the end of the day. (The particular syntax highlighter gadget has previously been noted as failing in that regard and its author has been recalcitrant in correcting the issue. It is his choice to do so, but given his recalcitrance I would suggest that tool as a terrible example. The syntax highlighter natively supported in 2010 and 2017 wikitext editors by MediaWiki has no issue parsing most constructs of this sort [though amusingly enough the templatestyles tag itself has an issue, phab:T263694].) --Izno (talk) 19:58, 22 December 2020 (UTC)

Lua in-module templatestyles
What are the options to apply an existing .../styles.css into a module? For example, use {{Frac}} hardcoded into the module. The TS required is not known (=dymamic, by template input), so defining the TS in the implemented template (before the module call #invoke) is not possible. Any examples? -DePiep (talk) 11:28, 8 May 2022 (UTC)
- You can load templatestyles from a module in the same way you can call out to any other extensions tag. with frame:extensionTag. An example can be found in Module:Sidebar, for instance. Just make sure to output it in a sane spot (generally before the content). —TheDJ (talk • contribs) 12:19, 8 May 2022 (UTC)
- Module:Convert is too complicated but searching it for
add_style
andget_styles
shows a generic solution. The code callsadd_style
when it knows a certain style is needed, andget_styles
is called to get all the styles (if any) which are then output before the normal convert result. Johnuniq (talk) 23:53, 8 May 2022 (UTC)
