I tried it before, Sourmaps sounded amazing, like the future I wanted to have! However, it didn't work for me last time, partly because of Compass, partly because it was at a early stage. Now however, the technology have evolved, I'm past the compass days and Libsass and Gulp are my new best friends.
Over the years I have been using several techniques to do ui graphic in front-end development. Lately I have used svg-sprites, and this is how I made it work on my web site.
Once in a while I learn small tips and tricks that I wish I knew before. That happened recently when I figured out how to paste text and at the same time remove text formatting.
Adjusting colors with a css preprosessor like LESS and Sass is really great, but the result is not always how you would expect. I explore alternatives to the lighten and darken functions, and compass have a few tricks up its sleeve.
