I am having trouble with modules being smaller than the pictures I put in them.  I am doing some amazon links into iframe modules and the image link overlaps the module boundary the image will then run in modules that are next to it?  Can you make the module "container" invisible behind the image?  Some of my link images can't be resized.  I wondered if there was a way to somehow hide the white background in the modules? I have attached a pic for a visual. Notice the Amazon ad and how it runs over the module boundaries, also notice the skyscraper ad on the right...there is a lot of white on the right of the picture.  I have selected the "center" option in the settings but it didn't change anything, even if the skyscraper ad could be centered in the white it would look better; however, I'd like to eliminate the white background if nothing else or at least make it transparent.

Thanks!s 

I'm just learning this platform, how do I go about making the change with CSS?

I also have tried multiple times unchecking the "display container" box and nothing happens, that box is on the Page Settings tab.
