Yes, that's the main feature. \Css is meant mainly for smaller chunks
of code and for your custom tags. Design for the whole page is better
to be put in an external file. Another upside is that when you fix
something in the CSS, you don't need to recompile all documents.

TeX4ht doesn't read that file at all. It is declared as used, so when
you use the --output-dir option, TeX4ht will try to copy it to that
directory, but other than copying, it doesn't do anything.

As you want to use it on your webpage, I think you could place the CSS
file to a directory on your server, for example:

https://www.12000.org/css/design.css

You can then use

\Configure{AddCss}{/css/design.css}

Web browsers should find the file and use it, because they can use
relative addresses.
