At default all pages will have a clean white top section with the page name in the middle.
You can change this by adding a header image with custom content.
You can achieve the by doing the following:
Go to the page in your WP backend
Scroll down the page to the bottom where it says “Header Settings”
Here you can choose to have a background image or just a blank area
You can set the height of this area and add you own custom title and excerpt
The header will use the global H1 style. Can be set under “Typography”.
You have the ability to override the color of your global H1 color by adding a Header Font Color at the bottom of this page.
