Every other feature has a white background – need help to change.

You can see my issues here. https://homeschoolcheer.com/directory/add-listing/ Every other feature has a white background. I find this to be visually aggressive and would prefer the features to be on the same background.

I’d like all the features to be the same tan/olive color. It looks like this code (below) is the culprit, but that’s where my code ability ends. I feel like I should be able to change this in the design setup, but don’t have anything set to be white so I’d love some help figuring out where to change this in the design css.

Thanks!
