Framework

For when you don't want all that bloat but you need a navbar with a dropdown.

Google's open source UI toolkit for building compiled applications across mobile, web, desktop, and embedded platforms from a shared codebase.

Bundles Vue into a complete development and build framework with a ton of options on how it's deployed to production. Comes out of the box with code splitting, live reloading, debugging tools, etc. Everything you need to fast prototyping without forgetting your project needs to be eventually deployed to production. In credibly powerful and I just can't imagine I'll ever roll a Vue app from scratch again.

This is as bare bones as a CSS framework can be. If your needs are just enough to want a (prebuilt) grid system but nothing more this is a great starting point.

A fresh take on frontend development that shifts much of the framework work into the compiler, producing small, fast apps with a simple authoring experience.

The problem with all CSS frameworks is they prescribe to one degree or another an overall layout and design. Picking the right one is generally a challenge of finding one that meets the needs and goals of your application or site. I would argue Tailwind is not in fact a framework at all but rather a toolbox of unopinionated utilities from which you can build your own framework.
