Editing Module talk:Sidebar (section)

== Title always link-blue? ==

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.: [[{{FULLPAGENAME}}]]) 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 {{tq|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?

:{{replyto|DaZyzzogetonsGotDaLastWord}} On which page do you see this happening? Examples ''always'' help. --[[User:Redrose64|<span style="color:#a80000; background:#ffeeee; text-decoration:inherit">Red</span>rose64]] &#x1f339; ([[User talk:Redrose64|talk]]) 21:03, 29 July 2025 (UTC)

:::This also occurs using Firefox, again dark mode only. The HTML that is served has <syntaxhighlight lang=html><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></syntaxhighlight> In both dark and light mode, this comes with the following CSS: <syntaxhighlight lang=css>@media screen {
  a.mw-selflink {
    color: inherit;
    font-weight: bold;
    text-decoration: inherit;
  }
}</syntaxhighlight> 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: <syntaxhighlight lang=css>@media screen {
  html.skin-theme-clientpref-night .mw-parser-output .sidebar:not(.notheme) .sidebar-title-with-pretitle a {
    color: var(--color-progressive) !important;
  }
}</syntaxhighlight> The last three simple selectors (<code>.sidebar:not(.notheme) .sidebar-title-with-pretitle a</code>) are what's causing the color to be overridden. The color value (<code>var(--color-progressive)</code>) is read from a variable that is set elsewhere. Why it's written that way, I don't know. --[[User:Redrose64|<span style="color:#a80000; background:#ffeeee; text-decoration:inherit">Red</span>rose64]] &#x1f339; ([[User talk:Redrose64|talk]]) 07:10, 30 July 2025 (UTC)
::::I did some [[WP:WikiBlame|WikiBlame]]-ing and discovered that  the last bit of CSS in your comment (the <code>@media screen</code> one) was added in [[Special:Diff/1234103998|this edit]] to the style page by @[[User:Jdlrobson|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).{{snd}}[[User:DaZyzzogetonsGotDaLastWord|Daℤyzzos]] ([[User_talk:DaZyzzogetonsGotDaLastWord|✉️]]&nbsp;•&nbsp;[[Special:Contributions/DaZyzzogetonsGotDaLastWord|📤]]) 13:20, 30 July 2025 (UTC)
