Default Theme Designs

This section of the guide focuses on helping you understand what the default theme design options in Pressbooks are and how they function. Each of the six default themes will affect the look and feel of your project across web, PDF, and EPUB formats. We additionally point out where you can find the option to modify the Cascading Style Sheets (CSS) for all three formats, noting here that the CSS and HTML chapter that follows goes into the mechanics of modifying the default design using CSS.

Considering modifying the default theme beyond the theme options provided as part of your Pressbooks project with Concordia University Library? If so, please include your intentions to customize the CSS in the project plan for your Open Textbook or Open Guidebook. We additionally recommend outlining your plans by adapting our Concordia Open Textbook Design Plan to your needs.
