Prevent Google Ads from overlapping

Hi,

I really love your theme and I’m planning to roll it out on my production site. I’m rather novice at coding so the changes I’ve made are about as good as I can get.

That said, I’ve run into a problem. I’ve created a custom widget that is intended to display an google adsense ad under the featured image from within an article. I’ve added it using your recommendation of a child theme and everything is working except that it overlaps at lower resolutions and on mobile devices.

What I need it to do is disappear when the screen is smaller in the same manner the one in the footer is doing.

Here’s a page so you can see an exmaple:

You’ll notice if you reduce the resolution the banner in the bottom gets cut off while the one in the article body overlaps the sidebar.

I’m guessing there’s something that can be added to CSS but my hours of testing and searching have not lead to a solution.

If you can perhaps point me in the right direction I’d be very grateful.

Thank you!

Greg
