Why the ESL Web Components Library?

Browser Support

Our web components library uses built-in browser functionality — Web API and ECMAScript 6 features that are fully supported by modern browsers such as Chrome, Firefox, Safari, or Edge.

If you want our UI component library to work in older browsers, you can use one of the polyfill lists — "light" or "full."
