How do you remove the rounded square backgrounds?

^ Like, how there's a light pink bg on all of the boxes, and then a rounded white border?

How do you remove that?

I've been trying for an hour and I can't figure it out.

I'm new to coding profiles. : P

.block { background-image: none; border: none; }

Thank you so much! :3
