SUIT CSS
SUIT CSS provides a reliable and testable styling solution for component-based web application development.
CSS Modules
It is a CSS file in which all class names and animation names are scoped locally by default. The key words here are scoped locally. With this, your CSS class names become similar to local variables in JavaScript. It goes into the compiler, and CSS comes out the other side.
Material Design for Angular
Material Design is a specification for a unified system of visual, motion, and interaction design that adapts across different devices. Our goal is to deliver a lean, lightweight set of AngularJS-native UI elements that implement the material design system for use in Angular SPAs.
Animate.css
It is a bunch of cool, fun, and cross-browser animations for you to use in your projects. Great for emphasis, home pages, sliders, and general just-add-water-awesomeness.
Tailwind CSS
Tailwind is different from frameworks like Bootstrap, Foundation, or Bulma in that it's not a UI kit. It doesn't have a default theme, and there are no build-in UI components. It comes with a menu of predesigned widgets to build your site with, but doesn't impose design decisions that are difficult to undo.
