    Semantic is a UI framework designed for theming.

    Key Features

    • 50+ UI elements
    • 3000 + CSS variables
    • 3 Levels of variable inheritance (similar to SublimeText)
    • Built with EM values for responsive design
    • Flexbox friendly

    Semantic allows developers to build beautiful websites fast, with concise HTML, intuitive javascript, and simplified debugging, helping make front-end development a delightful experience. Semantic is responsively designed allowing your website to scale on multiple devices. Semantic is production ready and partnered with frameworks such as React, Angular, Meteor, and Ember, which means you can integrate it with any of these frameworks to organize your UI layer alongside your application logic.

    Semantic UI is now compatible with Node 18 and Gulp 4.
