I'm glad I found this thread! Grid seems like part of a puzzle I'm piecing together.
I've been taking a web dev bootcamp from udemy (the Web Developer Boot Camp 2021, by Colt Steele), because it's time I updated my geocities era web development skills.
I just got to the layout part of the course, where they teach flex box, which seems nice, but they say it's new, within the last year or two. Last time I laid out web pages, I did it with tables, and I used iframes maybe once or twice. So I have this big gap in my knowledge of how web sites are laid out. What happened between tables and flex box?
I don't expect a huge encyclopedic explanation, but maybe somebody could give me a quick list of things to search for to catch up on what I missed? I'm finding it surprisingly difficult to trace the history of things like this.
