Hi @jaime.villasenor
The editor is a mix of HTML and JavaScript. Most of the heavy lifting is done in JavaScript. I can't recall what's specifically in HTML5... What do you want to know?

The editor does indeed use HTML v5 by definition since the opening 2 tags are ``. I think that there probably should be a `lang` attribute on the html tag but you do have the meta charset tag set to utf-8 which I think is the most common setting for modern html.
Here is a basic html5 template: [HTML5 Template: A Basic Boilerplate for Any Project - SitePoint](https://www.sitepoint.com/a-basic-html5-template/#thecompletehtml5boilerplate)
I couldn't even find an example of an older version of html now. However, there were several variations and a choice between xhtml and html standards.
