Hola, amigos. For the last month or so, I’ve been experimenting with the power of CSS pseudo-elements, specially when it comes to mixing them with buttons and that way recreating some great effects that were only possible to do with sprites, in the past.
In this tutorial, I’ll show you how to create buttons with a twist, using just one anchor tag per button and the great power of CSS.
