We are building a PWA using AngularJS targeting Mobiles, Tablets, Laptops and Desktops. Like for smaller to larger screens. This is our first PWA and my first project in Angular. We are confused between PrimeNg and Bootstrap. I read in an article that PrimeNg has got Bootstrap implemented in it from 5.x.x version. Which is the best Framework for this?

I'm building, from scratch, a webapp. It's going to be a dashboard to check on our apps in New Relic and update the Apdex from the webapp. I have just chosen Next.js as our framework because we use React already, and after going through the tutorial, I just loved the latest changes they have implemented.

But we have to decide on a CSS framework for the UI. I'm partial to Bulma because I love that it's all about CSS (and you can use SCSS from the start), that it's rather lightweight and that it doesn't come with JavaScript clutter. One of the things I hate about Bootstrap is that you depend on jQuery to use the JavaScript part. My boss loves UIkIt, but when I've used it in the past, I didn't like it.

What do you think we should use? Maybe you have another suggestion?
