Hey peoray, In my opinion flexbox is a “game changer” once you learn it. It greatly reduces the struggles with arranging page layouts and sizing.
Easiest way to learn the basics from my experience is to catch a 15 min video on Youtube and code along with it.
Once you have the basics down, start using it in your projects. This page has some great applications you can apply: https://philipwalton.github.io/solved-by-flexbox/
Bootstrap 3 does not use flex. Not a single line of flex property in it.
Bootstrap 4 is a different animal. Lots of flex.
This page helped me with flex.
I thought divs and floats was easy already. Flex and grid just made it event better. Although I haven’t hang up divs and floats yet.
Beneficial to learn all 3.
I’ve been using bootstrap, but I want to get away from it. I feel like I spend more time trying to override bootstrap styles than I would spend writing the css from scratch.
I’m interested in playing around with susy and flexbox.
