How to Make the Header Transparent
To make the header transparent, go to the specific page where you want the header to be transparent and click on the top section of that page.

Next, in the Section Tools located on the right side of the section, click the topmost icon to activate the transparent header.

For a section with a background image, the image will extend behind the header.
For sections without a background image, the header will take on the background color of the top section. This enables different pages to have differently colored headers when the transparent header is enabled.
