Page top displays are combined with your navigation, so they only occur at the top of pages. 

1. The default is no display - so you don't have to add anything. If you want to add a larger display your options are:
2. Content (a text overlay) include an optional rich text area and optional button with adjustable alignment and placement within the window, as well as content width – to best accommodate your background elements.
3. Media defaults to a photo or photos. More than one photo will trigger a slideshow. If you prefer a video, check the box.  Media elements are drag and drop.  
4. Multiple window heights from small to full viewport make this page top flexible for all sorts of displays. 

Your website default header displays on the colored background as the default if you don't choose a photo or video page top.
