Why does it remove :hover?

When I have this in my css

a:hover {
  text-decoration: underline;
}

and it gets inlined, then inline-css does not include them for links. Why?

I think the same process that preserves @media in the <style> element could be applied to pseudo-classes, pseudo-selectors, and @font-face as well. Basically, it would be great if any “un-inlineable” CSS could be preserved in <style>.

Whether you bundle those settings into one option or add flags for each one, I’m not sure.

Styles which can’t be inlined should be preserved in the style tag they origin from, imo. Basically this means all pseudo-elements (before, after, etc.), states (hover, active, etc.) and probably all @-rules (keyframes, media, font-face, etc.) and maybe even others should be preserved.

I’m not using this for emails only, so I think inline-css shouldn’t judge about support of those selectors for email clients but rather preserve everything which can’t be inlined.
