Creating a Theme

To create your own theme, start by duplicating any .scss file in /css/theme/source. Each theme does four things in the following order:

Include /css/theme/template/mixins.scss
Shared utility functions.
Include /css/theme/template/settings.scss
Declares a set of custom variables that the template file (step 4) expects. Can be overridden in step 3.
Override
This is where you override the default theme. Either by specifying variables (see settings.scss for reference) or by adding full selectors with hardcoded styles.
Include /css/theme/template/theme.scss
The template theme file which will generate final CSS output based on the currently defined variables.
