1# CSSTidy [](https://travis-ci.org/Cerdic/CSSTidy)
2
3CSSTidy is a CSS minifier
4
5* css_optimiser.php is the web-interface
6* class.csstidy.php is the parser
7* bin/pcsstidy is the standalone command line executable
8
9This class represents a CSS parser which reads CSS code and saves it in an array.
10In opposite to most other CSS parsers, it does not use regular expressions and
11thus has full CSS3 support and a higher reliability. The downside of not using regular expressions
12is a lower speed though.
13Additional to that it applies some optimisations and fixes to the CSS code.

23$csstidy->set_cfg('optimise_shorthands', 2);
24$csstidy->set_cfg('template', 'high');
25
26// Parse the CSS
27$csstidy->parse($css_code);
28
29// Get back the optimized CSS Code
