Mindy Body Widget Margins in Mobile - Huge??

Hi all,

Can someone help me with the coding that is necessary to make the margins around these embed code blocks smaller on Mobile? I get everything lined up nicely on the Desktop view, but I'm having to crazy overlap the code blocks and images on top of each other to shrink the enormous amount of space that is left otherwise.  Take a look at how closely I have to line up/overlap the code blocks in the Editor

I can't shrink any space under the "Buy Now" code block at the bottom, but when you look at it LIVE, there is a ton of white space. I'm sure this is some sort of coding I don't know how to do...
