Configuring a Handler

A error handler's configuration is determined by the arguments used in its construction. Here's an overview of these parameters.

require_once 'HTML/CSS.php';

$errorConf = array('error_handler' => 'myErrorHandler',
                   'push_callback' => 'myError',
                   // ... more options
                  );
$css = new HTML_CSS(null, $errorConf);
