I set up sections on each page to pull from the CMS. Every other section has a background color. When one section has content, it reflects on the other pages as an empty colored div. How do I add conditional visibility, i.e. if the CMS field is empty, the div doesn’t appear on published page? Thanks!

In general, conditional visibility is available only in collection pages.
In your case that you want to set certain color or size to a collection and hide if collection is empty, you can design the “Collection list” itself with bg color, size, padding etc.
Set empty state to hidden.
Add a filter to the collection to show only if content is set.
Done.
I hope this (work around) helped 
I think the only issue with that is if I make a filter on one project page and set conditional visibility in the editor, it won’t show on all the other pages right? Because it’s a global element
I stumbled upon this thread when I was trying to hide a div containing some CMS content.
For Webflow 2021 you can set conditional visibility under the element settings (cog icon) on the right-hand side of the designer.
Hope this helps anyone else looking for a similar answer!
@jaira Thank’s
That is the easiest and correct way to hide an element.
