Hello! I would like to know how I could create the following boxes that change color once you place your cursor on top and  once you click on the box the information below appears, how could I create something similar or exactly the same on Squarespace?
Thank-you so much in advance 🙂

With hover effect, you can add Text Block, then we can give the code

With info show in below, you can use Tab Plugin.
