function advagg_load_stylesheet

Loads the stylesheet and resolves all @import commands.

Loads a stylesheet and replaces @import commands with the contents of the imported file. Use this instead of file_get_contents when processing stylesheets.

The returned contents are compressed removing white space and comments only when CSS aggregation is enabled. This optimization will not apply for color.module enabled themes with CSS aggregation turned off.

Paramètres

string $file: Name of the stylesheet to be processed.

bool $optimize: Defines if CSS contents should be compressed or not.

bool $reset_basepath: Used internally to facilitate recursive resolution of @import commands.

Return value

string Contents of the stylesheet, including any resolved @import commands.
