I just have one really simple question - does anyone know if Subeta allows the :before and :after selectors in CSS? Because my coding works just fine in JSFiddle and then Subeta just seems to completely ignore the coding.

Pretty sure they work. I'm think I've used them before.

You may need to change some things. As far as I can remember for the content('') part you have to use ' rather than "

This seems to work. Thank you! Didn't realize it wanted single quotes instead of doubles.

SELECTOR:after{content:'xxx';}
