Uche Ogbuji has published a tutorial on how to use theopen source CSS preprocessor, LESS, to write readable and maintainable Cascading Style Sheets (CSS) for modern websites. CSS makes the terrible old days of layout tricks with tables and invisible images a dim memory. But CSS is still unfriendly, and several initiatives tried to tame it for developers. One of the best is LESS, which extends CSS with dynamic behavior such as variables, mixins, operations, and functions. LESS is a CSS-like language that compiles seamlessly into CSS either on the client side or through server-side preprocessing.
