[Edit Styles] is located over the page’s “preview” on the "Editing PhyID" tab.
From the "Edit Style" window, you can choose the page’s Header Image, Profile Image, Title, Description, and Background Gradient. All are optional, so you can have a profile without a Header Image, a Title without images, etc.
The preview will change dynamically so you can experiment.
[Save] when you get the look you want. Edit at any time in the future.
