use custom elements

Describe the Problem

Instead of divs use the editor defined container names as custom elements

Propose a Solution

custom elements have been around since html4. Why not use the user defined container names as custom tags?

Additional Context

<e-main-container></e-main-conteiner> would help navigating and trouble shooting custom styles, ids and classes
