Is is possible to put a very large image as a background image in the header/menu area. And then have the rest of the website slide up over it. Here is an example site. http://rocksaucestudios.com/case-studies/talkit
Set the page’s Header visibility and transparency to Transparent or Glassy Header then add a Color Section with background image or sliders at the very top of the page. Set the background attachment to fixed.
