Maybe this is a pretty naif question, but I’m not able to figure out how to do it. I have a website in which I want to show four images at the end of each post, and I need those four images to always be shown in two columns and two rows (2 and 2), not the four in a row or the four in a column. And I need them to always stay that way, in that layout, regardless of the size of the screen they’re displayed on. Any advice? Thank you very much!
