Cannot apply custom CSS via theme settings With Drupal 7.x and the Whitejazz theme, I want to apply custom CSS styles to some elements. This theme has the option to include custom CSS styles by specifying the path to the CSS file (in Appearance > Settings). 


  


I created the folder and uploaded my file, specified path, but this doesn't work for me, even after clearing the cache. I can apply my styles using the CSS injector module without a problem, but I want to find out why I can not set this using the theme settings.
I think the problem is that you forget to add a reference statement in your theme's info file.
like this:

stylesheets[all][] = css/layout.css


After that, need to clean the cache.
