I am looking for an experienced ScrollMagic developer to recreate a scrollmagic implementation into a wordpress site. The particular behavior that I want recreated can be found on this page: https://www.invisionapp.com/enterprise Please see attachment for screenshot of the particular section.
Essentially, I need a section with full screen background image pinned to the top and display inner sections while scrolling with a fade out, when inner sections reach the top of the screen. There are 4 inner sections that need to show whole scrolling. On the second pair of content I also need the background image to fade into a different image. Finally, this needs to work both on scroll down and in reverse on scroll up, regardless of how fast the user is scrolling.
I have already coded this in a certain way but the results are not exactly as I want them. It would be great if the same behavior works on mobile (just like the example) but this is not necessary. I am happy for this to work only on tablet and below.
I already have staging environment setup and will provide access to the files (via SFTP) and backend of WP.
