H2JS Element Class

A simple javascript class for creating self contained, reusable, ui elements.

Custom DOM elements as easy as vanilla javascript objects.

• Reusable components -- as simple as an import.
• Styling encapsulation -- use css without concern for the global scope.
• Complex UI elements -- UI elements can contain UI elements.
• Flexible -- elements can be used on their own or with other frameworks.
