This looks like a great resource! Like others, I vastly prefer an example-based style, and the examples are really well chosen and very illustrative. I generally think I know my regexes, but I've already learned a few tricks. (Backreferences to match different delimiter options but not mixed delimiters is very cool!)

Feedback:

The highlighting of matches is slightly shifted to the left for me in Firefox 75 but not in Chrome (both on Ubuntu 16.04). The shift is subtle but enough to make me have to look two or three times at most examples, as the highlight covers half of the character before the match and only half of the last character in the match. Can I suggest adding Firefox to your test regimen, if you haven't already? :)

Also, on the Anchors page, I believe "carat" should be spelled "caret."

Thanks for this once again! I will definitely be revisiting this site to brush up and learn new tricks. Especially lookaround, which I have never quite wrapped my head around!

Oh, I thought I had fixed that. I primarily test with Firefox, so this is a bit of a surprise. I'll check it out—I think it's something to do with CSS's `letter-spacing`.

I've fixed the typo, thanks for pointing it out.

Thanks for the comments!
