Help with bubble.is

I need help with two parts of website development with [login to view URL] (was [login to view URL]). Part 1: I need to know how to make groups (with an image background) height to be set responsively to view-port height. A button/scrolling will focus/move down so that the next group is also the view-port height. I have tried "[login to view URL]" but it freezes the page (but not the floating group at the top). One website I would like to implement this on is "[login to view URL]". Part 2: A better way to manage "scrapbook style" image layout within a group with multiple partial overlaps. They need to work with all screen sizes. These can be seen on the page "Activities" of the above site. For example go to the slide that says "The culture of Bali is a few steps from your front door". If you are only able to do one of these then that is okay just put that in your response. Deliverable: Part 1: A page with 2 single image groups groups and a floating header each at view-port height. Part 2: A page with two groups in a slideshow (preferably also at view-port height if you are also doing part 1) with "scrapbook style" images and arrows as discussed above.
