Worked on StyleURL over the past couple of weeks with my friends Jarred (most of the code) and Lucy Guo (design). The goal is to make it super simple for designers & front-end devs to make changes to CSS on websites and export those changes into a gist[0].

We made an open file format called “Stylefile”[1] that the extension parses to apply shared changes to sites. Eventually, we want to support stylefiles on other platforms than just GitHub.

It was definitely inspired by something that we wanted for ourselves, as well as a reaction to the scummy behavior of Stylish....

It was really fun building this, especially writing the stylesheet diffing module, which diffs two stylesheets and prints the difference as valid CSS. It's open source[1], as well as the rest of the extension[2].

We're not really sure what to build next, or if this is even useful. Please share any feedback, especially what you might use it for.
