We’re adding yet another perk to PressbooksEDU networks: a discussion space in our Pressbooks Community specifically for network managers of EDU hosted networks. All current and future PressbooksEDU network managers will be invited to connect, interact, and share ideas with others in similar roles in this forum. Our decision to create this new community space
At Pressbooks.com, we have more than 50 different book designs to choose from. Still, sometimes our users want to adjust the design of a book theme to make it unique to them or to fine-tune one aspect of a layout to serve the needs of a particular book. Pressbooks supports that! Generally you can customize most elements of your theme in your book’s CSS. If you don’t know CSS, that process might seem intimidating, but we’re going to do our best to make it easier here.
What is CSS?
To understand CSS, you first need to understand the concept of “styles” for graphic and Web design.
Smart designers have long used what’s known as “style sheets” to design books, Web sites and more.
A style sheet is a master reference that tells a software to render all elements of the same kind in the same style–to make all second-level headers bold, for instance, or to make all paragraph text a certain font.
The benefit to styling a document this way rather than styling each element individually is the ability to make universal changes throughout your document. So instead of making the same change thousands of times, you only have to make it once. This means not only can you avoid that laborious process of styling each element individually, you won’t have to undo that design line by line if you ever want to change it.
How to Get Into Your CSS in Pressbooks
Pressbooks allows you to customize your CSS to get a design unique to you. It also lets you customize CSS differently for your different outputs: Web book, ebook and PDF (print) book.
To customize your CSS, you must first apply the “Custom CSS” theme. To do this, go to Appearance / Themes / Custom CSS and click Activate.
Next, click on Edit CSS on the left dashboard. (Important Note: This option will not appear until you’ve activated the Custom CSS theme.)
Don’t worry. You don’t have to start from scratch–you can tell the Custom CSS to “inherit” the styles of a pre-built theme.
Specify the theme you’d like to start with for the Web, ebook and PDF versions of your book.
If this isn’t clear yet, this video may help walk you through it.
How to Customize Your Book’s CSS
If there’s something you want to adapt in Pressbooks, chances are you can do so in the CSS.
Here are just a few examples of elements you can modify using CSS:
- font family
- font color and size
- paragraph spacing
- text alignment
- what length of word is considered a widow or orphan
This chapter on CSS in our User Guide gives more information on how to customize these elements using CSS.
