Possible bug? The `hover me` seems to be implying that hovering that text should highlight something in the code sample, but nothing is happening. I assume that's the goal anyway - mouse over sections of explaining-text to see the highlighted-code that's relevant. (both "highlight word" and "highlight lines" could be handy here. tbh I'd probably use "highlight lines" more often)

Ignoring that: this is pretty nice looking, both the explanation (clear and with good examples) and the component itself. Good work!
