Never mind. My hosted account is the fault. With web sharing turned on, "http://localhost..." worked just fine. Sorry to clutter the list with now two messages.
To be honest, I can't tell if the failure to apply a style sheet is something odd in my TM set up or something flakey going on with my hosted set up. Would someone mind reminding how to make the call to a local style sheet so that I can test what's going on?
Is it "file:///path/to/file.css" or is it "http://localhost/path/to/file.css " -- and with the latter I assume I have to have the built in web server running, yes?
