Overriding css file in theme.info not working as expected

Question

I am trying to remove nice menus css, as per the notes in my Zen theme .info file. I have added the below to the info file, and I haven't provided replacements in my theme so they should be removed.

stylesheets[all][] = nice_menus.css
stylesheets[all][] = nice_menus_default.css

However they are still being imported. Cache cleared.

Thanks

EDIT: I'm aware this can be achieved using hooks, but would like to do it at theme .info file level, unless I am mistaken and it is not possible to remove contrib module .css in the theme .info file.

Answer 1

You can remove the css file of particular module

function MY_MODULE_css_alter(&$css) {   
unset($css[drupal_get_path('module', 'views') . '/css/views.css']);
$css = array_diff_key($css, $exclude);  
}

Answer 2

Try disable/enable theme. Yes it likes a trick. It seems info files are parsed when modules/themes are enabled/disabled.

Answer 3

you can remove(alter) css files with hook_css_alter, here is a simple example:

function MY_MODULE_OR_THEME_css_alter(&$css) {
    // dpm($css);
    unset($css[drupal_get_path('module','system').'/system.menus.css']);
}
