These do not appear to be accessible at all.
If you use this on your site, I will not be able to read whatever you're trying to tell me, other than by making me look at source.
Please don't do that.
I know accessibility is hard, and the developers of this were just trying to make something that looks nice and gets the job done.
Every time an inaccessible reusable {component, library, toolkit\, framework} is released, the inaccessibility spreads like a cancer to every single downstream project.
What this translates to is a web, that for me, is slowly going dark.
This sucks, but I don't see any way to fix it other than trying to be some sort of front-line accessibility cop when I see new stuff on HN.
But I'm not an expert in all forms of accessibility, and I am already stretched thin trying to build my own accessible apps.
I don't have a good answer here, just a plea to consider accessibility when designing stuff that's meant to be some variety of reusable widget.
