Provide permalinks for headings

[mcking65]

would be nice if we provide anchor links in the headers, There's no longer # in headers which I can click and get the link of the section.

For example in this page
https://www.w3.org/WAI/ARIA/apg/practices/keyboard-interface
There is no way to link to the roving tabindex pattern directly.

Fun fact: although attaching the old hash does work /#kbd_roving_tabindex

The TR Note offered permalinks for all headings, so the fact that we no longer have them is a functional regression.

@shawna-slh, would you prefer this be addressed by a template feature? Or, would you prefer that we make it an APG feature?

Users can get links to a specific section by clicking in the Page Contents list and copying the URI. That's not as easy as a permalink UI, though.

I would prefer this be addressed site-wide -- WAI-site-wide, if not W3C-site-wide.

I'm pretty sure that @yatil developed UI for permalinks on WAI website a few years ago; however I can't find it. (I think was on the old tutorials.)

If you can't find that, please use W3C site implementation.

That only works for level 2. We have several sections where it is valuable to link to level 3 or 4 headings.

So, there is a w3c site implementation we can re-use now? How do we do that?

I don't think the 2014-ish implementation of the tutorial one would stand muster in 2022.

There has been no re-implementation for the redesign as there were other priorities.

There is probably a good way to use the Web Share API: https://developer.mozilla.org/en-US/docs/Web/API/Web_Share_API

Thanks very much for the reply, @yatil !

Agree.

It's easy to include additional heading levels in the Page Contents List if we want.

Without looking at it, I'm guessing that we don't additional levels because the Page Contents would be too long.

However, if others think it is best, I would support that. For example, if you think users will often want to jump down to an H3 or H4.

Please ask the W3C Systems Team via e-mail to sysreq@w3.org
Please also CC: team-site-design@w3.org

We might also need to get Steve's help at some point for the WAI site integration.
