Umm..your CSS example doesn't show any template includes. No way to put header/footer in separate files.

but they are in a separate file. the css file. you an load multiple css files if you want to break it out.

That's strange; the `head` and `footer` nodes were present in the XSL template this morning [1], last GH change was Feb 13 [2], what matches

    curl --head --silent --url https://xsl-website.widloski.com/template.xsl | grep modified

		The footer is in the stylesheet in both my and Evidlo's example. In neither of our examples are these in separate files from the stylesheet.
