I found a solution in an example on the D forum.

I won't outline the details of the changes I made, but here's the updated code for future reference. I will make this one cautionary note:

This is only a test. This code makes for one ugly demo. Use at your own risk. May cause disturbing nightmares or afterimages.

Great, as for the version information / feature availability. For
functions the documentation includes a Since: X.XX annotation for
functions that weren't available in X.0.

For the CSS options the documentation is a bit more lacing, but you can
use the GtkInspector to view the available css options and there current
values.
