I have a theme, and many subthemes, with the goal of creating a network of sites that are different, but share some resources (like the stackexchange sites do). What I want is to include lots of boilerplate css in the master theme, and then site specific css included for each subtheme. The problem I have is the CSS of the master theme is not being loaded in the subtheme.
The master theme:
name = Master description = Master theme core = 7.x stylesheets[all] = css/network_style.css
and the sub theme:
name = Red Theme description = specific theme for site in network core = 7.x base theme = Master stylesheets[all] = css/red_style.css
Ideally then, the master theme just has network_style.css, and the sub theme has network_style.css and red_style.css.
If I enabled the master theme, then the network_style.css is applied. If I enabled the sub theme, then only the red_style.css is applied. There's no css conflict, and the master theme isn't visible in the page source at all.
Where am I going wrong? I'm somewhat new to Drupal. I've gone through lots of documentation on the drupal site, and checked through all the drupal 7 specific stuff on theming. I've tried clearing the drupal cache, plus my browsers cache, even turning server on and off like a mad man.
