AffiliateBooster Theme supports multiple layout options out of the box. That means in 1-click, you can change the header of your website. The header options are present in the customizer. Head over to AffiliateBooster Theme Panel >> Layouts >> Header Layouts to see all the options. Here are all the options you will see.
As you can see, there are 6 pre-built header layouts. Click any one of them to change the header layout instantly.
Note that the image in the header option is not visible as it is an ad-space and will have to be configured separately.
You can also choose a background color for the header, or a background image as well. Here is an example.
