Confusing/broken sufficient techniques in 2.4.11 and 2.4.12

[yatil]

In 2.4.11 and 2.4.12 the Sufficient technique is shown as:

1. C43: Using CSS scroll-padding to un-obscure content Using CSS margin and scroll-margin to un-obscure content

I assume the “Using CSS margin and scroll-margin to un-obscure content” text comes from the text outside the link in the source code here (2.4.11) and here (2.4.12).

While fixing this in #3454, I wondered where the text inside of the link comes from, and it comes indeed from this technique in the source code: https://github.com/w3c/wcag/blob/4dfd63d49c148007570403bc108207b8662b8b22/techniques/css/C43.html

I assume that the technique was using margin and scroll margin and then was revised to use scroll-padding. The old file however seems to be sticking around, hence you get a weird situation where a link mentioning scroll-padding goes to a page explaining scroll-margin.

• Merge PR Fix display of technique C43 in Understanding (2.4.11 & 2.4.12) #3454 (when done).
• Make sure to publish the correct technique pages.

You're right that the original technique used the margin properties. After some feedback, it was updated to use the padding properties. There seems to be a fair amount of outdated files sticking around for some reason. I mentioned this particular one to @alastc in last Friday's backlog meeting.

Thanks for working on it.

Going back to look at this, I'm seeing different content to you.

If I go to the Focus Not Obscured (Min) Understanding document, I see the link text as using "padding" rather than "margin":

When I click on the link to see the C43 technique, I see the old "margin" technique:

The same thing happens with the "enhanced" criterion.

@fstrr You see the same thing that I saw. 😃 It's very confusing.

To elaborate further: The link content comes from the title of the correct technique, but the text after the link comes from the actual understanding document because there is text outside the link lingering around. On compile, the text inside the link gets replaced by the technique name. My PR #3435 addresses this superfluous text.

I've merged the update, but @iadawn will have to clean up old files the next time the informative docs are updated.
