It’s actually a bummer: you can’t use a <style> tag because some email clients don’t like them. Instead, you have to inline your styles in every element. the lack of :hover is just a side effect of that I think (although it plays out nicely here).

(While on it, can we also ban loading images from third-party servers?)

you sure can if we resolve to make a text editor instead of a web browser!

Hmm, that might not be a bad idea! We could ban CSS altogether: just leave some markup tags, maybe whatever you can do in Markdown + tables. No colors, no small print, no images. (We could even use something like gemtext as the format instead of HTML, but that wouldn’t be backward compatible with clients.)

But I don’t see any email clients with somewhat significant market share going through with this :(
