I am trying to target the home widget areas of my site and make them the same height . I am assuming it is done through CSS in the Additional CSS on the theme customizer. I’ve tried the different fixes I’ve found through google and they are unhelpful or don’t solve the problem.
Chrome’s Inspector Tools will be helpful for you here. In Chrome, right click on the area you’re trying to edit and look for the class names. This is a good primer on that: https://developers.google.com/web/tools/chrome-devtools/css/
If you can provide a link, I could also try to guide you in the right direction.
