Is your feature request related to a problem? Please describe.
Writing HTML is slow, and would be much faster if I could use emmet expansions.

Describe the solution you'd like
Support for Emmet expansions (examples here https://code.visualstudio.com/docs/editor/emmet).

As a basic example, I could then type

.my-element#id

After pressing tab, it would be expanded to

<div class=”my-element” id=”id”></div>
