Thanks for the fast reply.
I am using Polymer 3. I will look into LitElement more, I am just trying to
be able to use Polymer enough to use with my other projects just in case.
The $ worked well. The LitElement way sounds a lot better.
Do you know how the get template Polymer function works? It is a little
confusing that a variable can not be used. Why is this?
I just joined the Slack channel. Thanks.
