Did you see https://sourceforge.net/p/docutils/feature-requests/57/
"add vh and vw as allowable length units"?

In Docutils, we must take care to properly implement this for all supported
output formats (HTML, HTML4.1 + CSS1, LaTeX, ODT, manpages, XML)

This means we need to figure out what these units will be, e.g., on a
printed output or how to give adequate feedback if an output format does not
support the respective unit.

Suggestions welcome.
