Any links you've added to your book will be functional and visible in the following supported formats:
- Digital PDF
In these formats, links will by default display underlined and in a different color so that they can be distinguished from the text.
In exported formats, links display in blue, though this can be adjusted using Custom Styles.
In the webbook, the color of links may depend on the settings of the Pressbooks network. On Pressbooks.pub, for example, links will appear in dark red in all webbooks unless manually changed by the book's administrator using Custom Styles.
In the print PDF format, links are not functional. Any links will display in the same color as the body text and will not be underlined.
