Timeless cancels out value of the cellpadding attribute
Closed, ResolvedPublic

Description

This is more of a documentation task than anything, but Timeless doesn't seem to understand cellpadding. I personally don't have a problem with this behavior (it will help identify off the cuff where changes should be made to bring Wiki* into the 21st century of HTML), which is why I'm noting it as documentation, but I might reasonably suggest this will be unexpected. 🙂

There are some other rendering differences there too on Firefox 57 on Windows 10, but that one immediately jumps at you.

Timeless uses Normalise (a CSS reset stylesheet) which applies a generic rule to td and th elements. See https://github.com/wikimedia/mediawiki-skins-Timeless/blob/master/resources/libraries/normalise.css#L409:

td,
th {
	padding: 0;
}

This CSS cancels out the cellpadding value as it has a higher specificity level.

To be more specific.. understanding what an HTML attribute and recognizing it, is done at at the web browser level.

Assuming the attribute in question makes it through the MediaWiki whitelist, which is what was confusing to me in general.

That would be MediaWiki's parser, which decides what to output to the browser.

Worth merging? The root cause is the same, even if infobox CSS is on Wiki* rather than in the skin.

In contrast to the other skins, Timeless sets border-collapse: collapse and border-spacing: 0 to all tables, including all tables in the content area. The issue can be fixed by just removing these two properties, or making their selector more specific so it does not cover inboxes and such.

General note that we might want both of those things, not just the one listed here.
