Thanks so much - I removed the footer with the CSS you sent me, and that helped. As for the Follow Me, I added display: none; and it still showed up but when you clicked "follow me" on a mobile device, a shadow would appear for a pop-up box, but the pop-up box wouldn't display. Luckily, I took a deeper look at the plugin and found that you could deactivate it for mobile devices, so I did that. The site looks *much* better on mobile now.
Now just to tackle the menu... it's a custom menu on the home page and it's not super attractive! also working on moving custom CSS to a child theme like you suggested.
thanks again for your help - i'm not sure i would have figured that all out on my own (or if i did, it would've taken me twice as long!).
