Every theme includes a number of different types for the header of each page. The number and kind of types available vary from theme to theme, but they all have at least four that can be applied to any and all of your pages.
Open the Pages sidebar by selecting the Pages tab. Select the page you’d like to change, then choose a Header type from the drop-down list. You can also change the header from the page itself, by clicking on the gear icon in the lower right corner of the current header. This can be changed later (and over and over again), so feel free try out different types to determine which one you’d like to use.
Let's take a quick look at the most common types.
Tall Header
This type is the default for each new page. It includes a section at the top of the page where a large header image can be uploaded.
Short Header
This type includes a header area at the top of the page as well. But as implied by the name, this header is smaller than the default "Tall Header" type.
No Header
You can probably see where this is going now. Where the Tall and Short Header types each have an area to upload a header image, this type does not include any such area.
Landing Page
The Landing Page type includes space for a header image, a title, a subtitle message and an action button that can be linked to any other page of your site. The Landing Page is a great choice for your home page.
Splash
With a Splash page, you get an entire image for the background, and you can add text and any other elements on top of the splash image.
With any of these headers, hover over the image and click Edit Image to change or alter the header image. You can choose from a large selection of high quality (and free) stock images, or upload an image of your own.
