Well I started in the 90s so I never used boostrap and always thought it was rubbish. That said, I could see how it gets you off the ground quickly.

I'd say... Use whatever you're comfortable with unless you want another problem to solve.

Nowadays the cool kids have all moved towards tailwindcss. It feels to me like a successor to bootstrap... It's bootstrap that only exports what it needs of itself. The problem is the disgusting html semantics that comes with it. How much do you have to hate CSS to duplicate weird class names, which are in essence a shadow of CSS within the code?... Over and over. It's like the 90s all over again and putting all the style within the html tags!

So I'd say, use bootstrap if you're comfortable with, it's fine, or roll your own.

I've used bulma[1] with some success for a small project, the problem is I always end up fighting the framework. It's hard to find one that doesn't limit you in some way, or pollute the namespace with a ton of junk you'll never use. On the other side of the stack you have tailwind which I'm becoming allergic to.

It's worth learning CSS, there is nothing hard. Most of my products/site are custom CSS. It's easy to jump back in and inspect old code. CSS stays CSS. Those frameworks come and go like the resume piece they started as.

Thanks. What I loved about BS was few builders that I could drag and drop bs elements into canvas. Then just copy&paste the generated html. I had 80% ready ui, without the need to adjust any color, padding or marging. - the thing that i hate about designers using sketch & figma. Makes the project 2x more expensive. Also tried bulma and buefy with vue but it had some serious limitations. And after studuing tailwind--that's just horrible. As programmer bootsrap gave out of the box gui blocks to use without a mess. Most stone-age thing that i've seen lately was Flutter - putting all the paddings and other style back in to same place as "business logic" javascript. That's just opposite of learning from your mistakes..

I wouldn't say it's obsolete. It still lives on, just the hype cycle has dipped to a trough. I prefer 'classless CSS' frameworks though. You just drop a CSS file into a HTML document and everything's already styled without having to write very much code or learn the 'lingo' of Bootstrap to get things done.
