LESS extends CSS with dynamic behavior such as varibles, mixins, operations and functions. As an extension to CSS, LESS is not only backwards compatible with CSS, but the extra features it adds use existing CSS syntax. This makes learning LESS a breeze, and if in doubt, lets you fall back to CSS.
The most powerful thing SimpLESS does: Save your *.less file and, BOOOM, SimpLESS generates a 100% valid standard CSS document out of it. No further steps, it’s that simple.
