Note: From now on, most of the new development on LESS will be happening in http://github.com/cloudhead/less.js

LESS

It's time CSS was done right – LESS is leaner css.

Setup

to get the latest development version:

sudo gem install less -s http://gemcutter.org

to get the latest stable version:

sudo gem install less

Explained

LESS allows you to write CSS the way (I think) it was meant to, that is: with variables, nested rules and mixins!

Here's some example LESS code:

@dark: #110011;
.outline (@width: 1) { border: (@width * 10px) solid black }

.article {
    a { text-decoration: none }
    p { color: @dark }
    .outline(3);
}

And the CSS output it produces:

.article a { text-decoration: none }
.article p { color: #110011 }
.article { border: 30px solid black }

If you have CSS nightmares, just $ lessc style.less

For more information, see you at http://lesscss.org
