You know all the CSS generators like CSSmatic or CSS arrow please? I was looking for something similar, but for Medium-style text underlines (using background-image) and, strangely, unable to find it. So here it is: underlin.es.

It’s called “underlin.es” like it was hosted on underlin.es, but it’s not. Originally I had the intention to, but at 1:30 AM I just wanted to get it done.
