Why isn't the block level element moving?

Question

Hey, I know this is a lot of code, but could someone shed light on why the h2 "Activities", isn't sitting BELOW the last of the 3 images in mobile view? it sits right below the first of the three images. I can't figure out why.

Thanks

its because of parents of floated elements are collapsing! add this to your css: #imost_popular_section{overflow:auto;}
