SASS is a CSS pre-processor. It allows the developer to take a more programmatic approach to writing CSS, harnessing the power to use mixins,partials,variables and more. http://sass-lang.com/
In our SKINS repo we write our SASS using the SCSS syntax
We build our new projects from our skeleton project which structures our SASS in verbose modules
We use standards when writing our SASS. Please adhere to these - SASS Coding Standards
Our grunt task runner is set to watch the sass files in your project. If you make a change the CSS files will be generated automatically
