UIkIt vs. Toolkit vs. Mozilla Brick

UIkit gives you a comprehensive collection of HTML, CSS, and JS components which is simple to use, easy to customize and extendable.

Toolkit makes use of the latest and greatest technology. This includes HTML5 for semantics, CSS3 for animations and styles, Sass for CSS pre-processing, Gulp for task and package management, and powerful new browser APIs for the JavaScript layer.

Brick is a collection of UI components designed for the easy and quick building of web application UIs. Brick components are built using the Web Components standard to allow developers to describe the UI of their app using the HTML syntax they already know.
