Hello guys, I hope someone can help out with my query. I'm trying to add a subtitle or a short description to my grid thumbs (I'm not too sure about the terminology for this button but please refer to the images for reference). I want it to be so that there will be an additional line/paragraph of a few sentences under 'Unit A' which helps to explain what 'Unit A' would be about. I know it's possible to override the settings using the Custom CSS but I'm not equipped with enough knowledge in that area and would really appreciate if anyone could help me out. Thank you very much for your time and kind attention!
