Share stylesheets among subthemes

Hi flodo,

At this juncture, this is how I would tackle this problem:

1. Create a regular LayoutStudio sub-theme. Let's call it "common", since it will contain the common CSS stylesheets
2. Remove all of the CSS files in the CSS directory, and add a common.css file
3. In the common.info file, remove all other stylesheets, and add a line for the new common.css.
4. Create all the sub-themes you need. For example, you mentioned a youth section, so perhaps a "youth" theme.
5. Whenever you create a sub-theme, change one setting in the info file that is not in the instructions: change the base theme from "layoutstudio" to "common"

I don't want to judge how good your skills as a themer are, but you should keep in mind that there is a general tendency to want to use new themes for site sections too quickly, without really using the theme's features to it's full potential. A few of examples of what I mean:

• Use the section body class: for example, if you have a "youth" section to your site, and everything that belongs in that section has "youth" at the beginning of it's path alias (ie mysite.com/youth/blog/blog-post-title), then you can utilize the "section-youth" body class that LayoutStudio provides.
• If you need to change the layout per site section, the LayoutStudio Extras module can do that for you.
• Create your own body class in a page preprocess function, or insert stylesheets dynamically based on page context.

Hopefully this points you in the right direction. Let me know if you get stuck somewhere.

thanks,
Rene
