Should there be a way to automatically open up the relevant section of the sidebar?

After Template:Feminism sidebar got reorganized, a bunch of transclusions no longer automatically expand the correct section. For example, the article Feminist theory in composition studies automatically expands the "Concepts" section even though the article is now listed under the "Theory" section. Something I realized is that expanding the section that contains a link to the current article might be something that could be done automatically, so that editors no longer have to manually specify the section to auto-expand on every article where a sidebar is included.

How get "alt" text for the image

Latest comment: 3 months ago3 comments2 people in discussion

In article Atlanta Compromise, it is using an InfoBox Template:Nadir of American race relations .. that infobox has an image in it. How can I add "alt" text for the image, to assist visually impaired users of the encyclopedia? I couldn't find instructions for alt text in this module page.

@Noleander: Template:Nadir of American race relations has

{{Sidebar with collapsible lists
...
| image = [[File:Le Petit Journal 7 Oct 1906 (cropped).jpg|232px|class=notpageimage]]
...
}}

and you would add the alt text inside that image specification using |alt=, see WP:EIS#Alt text and caption. --Redrose64 🌹 (talk) 12:57, 10 May 2025 (UTC)Reply

Great, thanks, that worked. Noleander (talk) 13:13, 10 May 2025 (UTC)Reply

Title always link-blue?

Latest comment: 1 month ago5 comments2 people in discussion

I noticed that when a wrapper of this template is called on the page the title parameter links to, the title renders as the link color despite not actually being a link. This doesn't align with the default behavior when a page links to itself (e.g.: Module talk:Sidebar) or the behavior when a non-title link in a sidebar links to the page it's placed on. It's also possible that this violates the Links should be clearly identifiable as links for readers clause of MOS:COLOR (it doesn't conform to the inverse, i.e. that non-links shouldn't appear as links).

My Lua knowledge is limited at best so I have no idea what/who (and, by extension, why) caused this. Any thoughts?

@DaZyzzogetonsGotDaLastWord: On which page do you see this happening? Examples always help. --Redrose64 🌹 (talk) 21:03, 29 July 2025 (UTC)Reply

First noticed it on Mathematics. – Daℤyzzos (✉️ • 📤) 23:22, 29 July 2025 (UTC) P.S. Just realized this—only happens on dark mode (probably should've checked that earlier, but oh well.) Also: using Chrome but also shows up in Safari on my phone (again only in dark mode). – Daℤyzzos (✉️ • 📤) 23:28, 29 July 2025 (UTC)Reply

This also occurs using Firefox, again dark mode only. The HTML that is served has

<table class="sidebar nomobile nowraplinks hlist">
  <tbody>
    <tr>
      <td class="sidebar-pretitle">Part of a series on</td>
    </tr>
    <tr>
      <th class="sidebar-title-with-pretitle">
        <a class="mw-selflink selflink">Mathematics</a>
      </th>
    </tr>
    ...
  </tbody>
</table>

In both dark and light mode, this comes with the following CSS:

@media screen {
  a.mw-selflink {
    color: inherit;
    font-weight: bold;
    text-decoration: inherit;
  }
}

which is what makes the word "Mathematics" appear black and boldface. But in dark mode only, the following CSS (found in Module:Sidebar/styles.css) is used in addition:

@media screen {
  html.skin-theme-clientpref-night .mw-parser-output .sidebar:not(.notheme) .sidebar-title-with-pretitle a {
    color: var(--color-progressive) !important;
  }
}

The last three simple selectors (.sidebar:not(.notheme) .sidebar-title-with-pretitle a) are what's causing the color to be overridden. The color value (var(--color-progressive)) is read from a variable that is set elsewhere. Why it's written that way, I don't know. --Redrose64 🌹 (talk) 07:10, 30 July 2025 (UTC)Reply

I did some WikiBlame-ing and discovered that the last bit of CSS in your comment (the @media screen one) was added in this edit to the style page by @Jdlrobson (pinging to find the reasons for the addition as the link in the edit summary is broken and a search for "Fall of Constantinople dark mode error" on talk pages turned up blank). – Daℤyzzos (✉️ • 📤) 13:20, 30 July 2025 (UTC)Reply
