CSS Feature Request: :last-child & clamp()

Support
#1

I was putting together a looper FAQ/accordion. Each item is separated with a line.

  1. Could there be a quick click to remove the border on the $el:last-child? Not that the CSS is difficult or time consuming, but it’d save some time if you could click on the border width and have a :last-child field.

  2. Would it be possible to add clamp() to font sizes? It’s a really nice feature and very smooth!
