# CSSTidy

CSSTidy is a CSS minifier

* css_optimiser.php is the web-interface
* class.csstidy.php is the parser
* bin/pcsstidy is the standalone command line executable

This class represents a CSS parser which reads CSS code and saves it in an array.
In opposite to most other CSS parsers, it does not use regular expressions and
thus has full CSS3 support and a higher reliability. The downside of not using regular expressions
is a lower speed though.
Additional to that it applies some optimisations and fixes to the CSS code.

## Usage

```php
include('class.csstidy.php');
$csstidy = new csstidy();

// Set some options :
$csstidy->set_cfg('optimise_shorthands', 2);
$csstidy->set_cfg('template', 'high');

// Parse the CSS
$csstidy->parse($css_code);

// Get back the optimized CSS Code
$css_code_opt = $csstidy->print->plain();
```
