Layui is a web UI component library, frontend layout framework, and CSS asset optimizer. It provides a collection of pre-styled visual elements and layout patterns used to build browser-native web interfaces.
The framework enables the composition of structured web pages through standardized design assets and CSS components. It includes tools for compressing stylesheets and resolving imports to improve loading speeds across different web browsers.
The library covers web UI development and frontend layout composition, facilitating rapid interface prototyping by assembling functional frontends from ready-to-use components.
