4. 6 wysiwyg.module \wysiwyg_get_css()

Retrieve stylesheets for HTML/IFRAME-based editors.

This assumes that the content editing area only needs stylesheets defined for the scope 'theme'.

When the stylesheets a theme uses are not yet known it will return a single URL pointing to a page which will gather the stylesheets so they can be loaded indirectly via import rules.

Note: if set to explicitly use the current admin theme by name, no access check on the 'view the administration theme' permission is performed.

Parameters

$theme: The id of a theme to get stylesheets for. Defaults to the current theme.

Return value

An array containing CSS files, including proper base path.
