1# 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. 14 15## Usage 16 17```php 18include('class.csstidy.php'); 19$csstidy = new csstidy(); 20 21// Set some options : 22$csstidy->set_cfg('optimise_shorthands', 2); 23$csstidy->set_cfg('template', 'high'); 24 25// Parse the CSS 26$csstidy->parse($css_code); 27 28// Get back the optimized CSS Code 29$css_code_opt = $csstidy->print->plain(); 30``` 31 32## Changelog 33 34* v2.2.0 : 35 * test suite switch to phpunit 36* v2.1.0 : 37 * fix issues with css4 colors 38* v2.0.0 : 39 * PHP 7.1 is the minimal version.
