Layui (homonym: class UI) is a set of open source web UI solutions. It adopts its own classic modular specifications and follows the development mode of native HTML / CSS / JS. It is very easy to use and ready to use. Its style is simple and light, and its components are elegant and abundant. Every detail from source code to use method has been carefully carved, which is very suitable for the rapid development of web interface. Layui is different from those front-end frameworks based on the underlying MVVM, but it does not go against the road, but believes in the way of returning to nature. To be exact, it is more for back-end developers. You don't need to get involved in front-end tools, just face the browser itself, and let all the elements and interactions you need come from here.
