Widget Mode Not Working

I'm trying to display categories in a .htm page using the layout widget from the store. But all I get is the cycling vertical bars which I assume means the javascript is trying to load. I do get the body background image so that tells me part of the script has loaded. What am I missing to use the widget code in another site?

Running 4.6.3

Created new Layout;

modified it by turning off some blocks;

pasted the widget code into the body of a simple html page

added the viewport code in Head

htm page is in root directory of the same store domain
