Basic Themes - mithra62/ee_debug_toolbar GitHub Wiki

To create a theme you basically have to do the following:

1. Create a folder in the themes/user/ee_debug_toolbar/themes directory. Give it the same name as your theme.
2. Create a directory in your theme folder called css. For example, themes/your_theme_name.
3. Create a file called ee_debug_toolbar.css in the css directory.

Be sure to take a look at an existing theme to get an overview of what classes are available. The Bootstrap theme is a good example of a basic theme.
