Skilling is built on Drupal, a popular open source content management system. Drupal separates the look of a site from the underlying data processing. The files that determine fonts, colors, logos, etc., are called a "theme" in Drupaland.
Skilling comes with a custom theme specially designed for skills courses. You can make a subtheme based on the Skilling theme. You alter just the things that need to be different, like colors and the logo. You can leave everything else alone. This means that:
- You save time, since you don't need to rewrite everything. In fact, you probably won't change very much at all.
- Updates to the Skilling custom theme won't erase your own changes.
