function cf_theme_safe_css in Common Functionality 7.2

A wrapper around drupal_clean_css_identifier that allows underscores.

Justification: Drupals core css cleanup code does not properly handle all allowed css, namely underscores. This is a quick-way to ensure that all non-word characters are removed from a string to be used in css.

Parameters

string $string: The string to cleanup.

Return value

string|false FALSE is returned if the preg_replace() functions returns something other than a string.
