21. The CSS Service Engine lesscss.org sass-lang.com learnboost.github.com/stylus

22. Design Engine Foundation: LESSPHP http://leafo.net/lessphp/ +

23. The Basics of a Design Engine //create new LESS object $less= new lessc(); //compile LESS code to CSS $less->checkedCompile( '/path/styles.less', 'path/styles.css'); //create new CSS file and return new file link echo "<link rel='stylesheet' href='http://path/styles.css' type='text/css' />";

24. Passing Variables into LESSPHP //create a new LESS object $less = new lessc(); //set the variables $less->setVariables(array( 'color' => 'red', 'base' => '960px' )); //compile LESS into PHP and unset variables echo $less->compile(".magic { color: @color; width: @base - 200; }"); $less->unsetVariable('color');

25. Implementing Color Functions Lighten / Darken Saturate / Desaturate Mix Colors Adjust Hue

26. Managing Irrelevant Content Remove / hide content based on user profile and state
