It has been proposed before ... This solution has the potential to work for other elements too. On the negative side: Did you chose <link> because <a> would be considered fallback ...? Isn't even <link> - until further - just fallback? In fact, so long as <link> is hidden in the fallback, then it is not keyboard accessible - regardless of whether you staff it with @tabindex=. And so, without some workaround for that, then the <link> would have to be placed outside the <video> element. > Similarly the tracks could indicate timed accessibility alternatives > via their "kind" label. > > And these are all useful for all users; a programmatic way to find > the transcript, description, and short text benefit all boats. In Firefox - and, I think, only in Firefox - the the <link> can, via CSS, become a visual, clickable element. In fact, it does not need any styling, so long as you add tabindex= to it or something like that. The problem is just: How to glue the link to the video in such a way that it is obvious that it is for the video. -- leif h silli
