Watch ths video I made myself. 10 minutes soup to nuts. https://www.loom.com/share/86a1ed0dac0c4814b2096f687a551799?sid=4894b011-5a33-4811-aed3-09cdb83bf7b1
THIS VERSION OF CMS GRID uses width % to determine break points, with <33 for 3, <50 for 2, <100 for 1.
It is very inelegant, this width-changing method. I hate it. Compare to the sytem I use to create card grids (non-Collection list grids) I prefer using a grid system, because in a grid system you just change the number of columns to make a new break point. It is very elegant. The problem I am facing mid-June 2024 is that I am having trouble doing this bc then I can't use flex and then I can't get all the cards the same size. I seem to have to choose between grid and flex in Collection List. Need to keep working on it.
