Div container not visible in Mozilla but is in IE? Why?

Hi guys, I have color coded the divs in question. In IE I can see my #wrapper (BLUE)and my second content container #secondcontainer (GREEN). But, in Mozilla I only see the blue of the #wrapper.

I’m not sure why this is, or is it even a problem?

Suggestions?

A quick fix would be to change your CSS just a little bit. In your col-12, col-c2, and col-r2, change it from float:left to display:inline-block.

It is a problem in firefox because you will have those div’s overflowing past your footer. So hopefully this helps.
