Formatting Messed Up on Home Page after editing keywords for pages?

Hello,

Our site is https://www.brandbundles.com. It uses the theme “Ventura” from themeforest.com. Twice now, we have had a formatting issues on the home page when we were editing things unrelated to the home page! Please see how, for one the “Portfolio” icon has fallen behind the slides. Also, see how all the text and our pricing table is no longer within the “front” box (I know there’s a more technical term for that) but it spans the full width from left to right, which is not how the other pages are set up.

We were only editing keywords on other pages when it appeared as though this happened. The first time, the theme developer helped us right away, but this time we just wanted to post here to see if someone could fill us in on how to fix it just in case it happens again in the future. We used the markup validation service (https://validator.w3.org) and saw many errors but aren’t sure where to start in fixing them.

Thanks for any help!
