If you're already familiar with CSS, getting started with LESS will be easy for you. In fact, with a background in CSS, you could probably learn LESS in less time than it actually takes you to read the rest of this chapter.

It works a lot like a programming language. Variables can be defined with LESS with an @ sign. Then, you can store a constant value that you can then reuse throughout your stylesheet. It's definitely a tool worth checking out.
