   CSS is a fascinating language! Very straightforward to implement, even if a bit weird.

   After lexing there's no need for backtracking, since its very prefix-heavy. Occasionally infix for media queries or math().

   It degrades gracefully (unless you're targetting Dillo browser) so you shouldn't have to worry about whether browsers support any given feature.

   Interpreting it involves little more than a filtered & weighted deduplication. With most of the optimizing going into filtering.

     Design-wise CSS represents a design-negotiation between your device (represented by the useragent stylesheet), the reader, & the publisher. Though in fearing The Cascade (aforementioned weighting) & not showing an understanding of HTML, publishers are making it harder for the others to have their say.

     So please, learn CSS Cascade Layers (which are available in browsers now, including mine) & HTML!

     at-import would've been easier if I wasn't implementing my engine in Haskell, but if you're going to remotely fetch multiple stylesheets anyways I've got no complaint... Just if you're worried about performance please don't nest CSS imports!

     P.S. You may want to combine at-import with Cascade Layers to avoid conflicts, there's syntax for that.

     @ekaitz_zarraga To me this makes no difference, they both parse to the same thing in Haskell Stylist.

     @ekaitz_zarraga If you at-import a stylesheet which at-imports additional ones, sure. Nothing the browser can do to optimize that, if you care about performance avoid it!
