I'm pretty confident these have been mentioned before, but thought I'd resurface them in a new thread: https://developer.mozilla.org/en-US/docs/Web/API/Highlight https://developer.mozilla.org/en-US/docs/Web/API/HighlightRegistry
Highlight takes ranges...which are hard for any mere mortal to create...unless they use Apache Annotator! ;) At any rate, I think putting a demo together that uses the Highlight API instead of <mark> would be useful, educational, and awesome.
