SASS is pretty great. If you haven’t heard about it, you’re behind. Study up cause I’m not going to explain it in great detail but the just of it is, that it’ll make writing CSS much more clear and concise. You can learn about it here.
I use Linux Mint or Windows to develop on. There’s step by step instructions on how to do this on the SASS website but basically, all you’ll need to install ruby:
sudo apt-get install ruby1.9.1
then install SASS
sudo gem install sass
done. That’s SASS installed.
