Bootstrap 5 alpha has been released so and showed you you know the new features and how to get set up and all that but you have been asked a lot lately should I learn bootstrap
so everyone has their own opinion some people hate bootstrap and hate css frameworks and would say don’t learn it it’s not worth it
whatever anyone that deals with the front end should learn it because it’s pretty easy to learn
But it’s not like learning a language it’s not like learning you know a framework like a javascript framework or a PHP framework or something like that it’s basically just memorizing classes and not even memorizing them just knowing where to look in the documentation.
so with that said I think that it’s worth learning but one thing it’s really important to learn first to HTML and CSS. you should be able to build a full website with a fully static website without bootstrap.
before you go ahead and learn either bootstrap or any CSS framework and as far as what you should learn in CSS but you not need to master it and learn like animation and stuff.
CSS BOX MODEL & FLEXBOX(Examples)
but I would say learn all the basics you know obviously colors and backgrounds and stuff the box model is really really important to understand.

and also learn positioning, flexbox, CSS grid so that you can align things properly without having to use a framework now with that said once you get those fundamentals down and you’ve built maybe a couple of sites by yourself without a framework.

then go into learning bootstrap and I think that it’s worth it because like I said it’s easy to learn and it’s good for people that aren’t really great with like design a lot of programmers don’t have a good eye for design.
so it helps them out helps them structure things if you’re not great with CSS like I said you should at least know the basics but you might not be great with it so you can use that on your front end maybe you deal mostly with the back end.
you don’t have to use the default colors and stuff like that you can change up the primary secondary colors you can include certain parts of bootstrap so you don’t even have to include the whole thing.
if you want to use cards and buttons and alerts you can just include those three things instead of including the entire framework which will save you on file size with bootstrap.
you don’t even need jquery anymore so file size isn’t really an issue anymore with at least going in to bootstrap 5
