Everything is an element

From <a> to <select>, elements are the building blocks of HTML. But modern applications have outgrown these built-in elements, forcing app developers to rely on JavaScript frameworks to provide dynamic, custom behavior. The resulting apps are frequently complex and monolithic; a component developed for one may not work in another.

{{site.project_title}} puts elements back at the center of web development. With {{site.project_title}}, you can craft your own HTML elements and compose them into complete, complex applications that are scalable and maintainable.
