button and image collapse

As in this video the images in the upper row collapsed and are coming over the content, but why in the lower row the button is coming over the images?

In the top row, there is just a div (photo-container) with an img in it. In the other 2 rows, there is a div (photo-container) with a div (photo, and photo slide) nested inside it, with another div (photo-overlay) nested inside that div. This puts the photo as the bottom layer, with the overlay on top of it. The css has it moved out of sight until you hover over it, where the photo-overlay:hover definition pulls it back in to view on top of the photo. The transitions on the image in the first row cause the image to move around relative to its original position, which causes it to be pulled out of the flow and float over other elements because the transition doesn't fundamentally alter the document structure.
