SASS

Sass is built upon Ruby. On OS X, Already have Ruby installed by default. If you may to install Ruby in Windows, use this Ruby Installer.

Sometimes developers need to adjust the output style of the CSS. SASS has four types of output style which make developers job easier.

Sass supports below four output styles.

Front end engineering has always challenge to choose right updated technologies, I have already updated SASS long back and used in many projects. It is really cool and very easy to manage CSS rules.
