template for HTML-- a favor

Dear Community Group,
 
Now that we have so many approved specifications,I want to ask a favor.
Attached is my old template for HTML. It has some basic CSS, and elements I
normally include.
 
If somebody could look at this and update it with the latest
recommendations, I would appreciate it. I would like to reference the proper
HTML 5.2, current CSS,  and also ARIA 1.1, and ourDPUB-Aria vocabulary.
While I don't know javascript, I think it would be great to at least have
the proper reference to this as well, in hopes of doing something with that
in 2018. I will be validating using the W3C online validator. 
 
Hopefully somebody already has this in their back hip pocket. Because I am
blind, I use the CSS to visually format my documents and know that it looks
OK. I will also use this template for testing various features with screen
readers and browsers. Oh, and I would probably also use it for chapters in
EPUB 3 publications.
 
 
Best
George
