i had the same exact opinion about myself until i tried starting a project with just bootstrap's reboot css file and realized that was enough to get a nice style and build on top of that

I need to sit down and learn flex css property so I can replace bootstrap row and col with flex.

Why not grid?

Why not both? Grid is superior for defining the overall structure of a page, but flex shines in micro-layouting. (Although the line between them is blurry sometimes).

TIL there's also grid.

And it seems to be well supported: https://caniuse.com/css-grid

Thank you.

If you are looking for a quick way to get up to speed with flexbox or css-grid you should check out https://flexboxfroggy.com/ and https://cssgridgarden.com/ They are fun little tutorial games that introduce the basics

Yes, and we'll be adding support for that as opt-in in v5.1.0! Here's a little teaser: https://deploy-preview-31813--twbs-bootstrap.netlify.app/doc....

Neat! I have been using Bootstrap for several years at work and for personal projects. It allows non-ux folks like me to build useable apps quickly. So thank you!

Same, bootstrap and bootswatch are a godsend.
