Div Block cloning and renaming

Hi, I’m trying to copy and paste Div Blocks so that I have the same properties on many of these filling up a section. However, when I Rename Class it changes the class name of each previous Div Block. How can I prevent this from happening so I can have multiple separate Div Blocks with small variations please? I’m sure this is super simple and I’ll kick myself when I see a reply. Failing that the relevant tutorial or cloneable site would make me very happy. Thanks in advance!

If you think I’m going about this the wrong way entirely please tell me… This is the page I’m trying to make a good version of… (please scroll down the page for interactive bricks I’m trying to replicate in Webflow. There will potentially be thousands on each page :grimacing:) https://brickproject.co.uk/bristol.html
