Re: highlighting code changes on an html page

Here's a note of something I've run into recently:
I use Windows High Contrast and use the main Black theme (I'm not picky so I don't make a custom one). If it occurs to you to try using the <mark> element with some roles or hidden CSS ::before text or whatever, be aware that for some reason <mark> text doesn't switch its colour like regular text does. I just ran into a site where the only way I could read text was to highlight it with ctrl-A.

It's not that <mark> offers any semantics but sometimes it feels good as a dev to use something that might be closest to meaningful and then actually make it work with AT with extra junk. But for this bug in WHC reason, I'd avoid it if it comes up in your thoughts :)

cheers,
Mallory
