Writing CSS (Cascading Style Sheets) is hard. Not only does it act different in all kinds of browsers. Its declarative syntax makes it sometimes difficult to write and to maintain. Just think about all the times you had to specify the same color code.

Enter LESS and SASS, two CSS preprocessors, which provide additional features currently lacking in CSS. They enable you to declare variables. You can create function with boilerplate code in it. You can nest CSS rules to keep track of the hierachy in yout HTML file. The end result is still CSS but by using LESS/SASS you can write CSS a lot easier.

This course will give you an introduction to both so you can decide which one you want to use in your web applications.
