The "Title Pages" that are created in a "Part" in Atticus are autogenerated; because of this, there is no direct way to edit the text size or styling. However, there is a workaround that gives you full control over how the page looks.
Create a Title Page as a Full Page Image:
You can design your Part Title page exactly how you'd like it in an external tool like Canva, then upload it into Atticus as a full page image and hide the autogenerated version. Follow the steps below for how to do this:
Design your Part Title page in Canva (or a similar program) with the text size, style or layout you want.
In Atticus, upload your design as a Full Page Image where you'd like it to appear in your book. Typically this would be before the beginning of each chapter in a Title Page.
After you've done this, you'll want to ensure that the autogenerated Title Page isn't included in the book.
To do this, click the three dots next to the autogenerated Part Title page.
Select "Include In" and then choose "None" to hide the autogenerated page.
We hope that helps!
