[BluffTHIS!]

I listed SSI as a method I didn't want to use. A site I am doing for a friend is hosted on a free server that doesn't have SSI stuff available apparently. I told him that he would most likely need to use a commercial server as I only agreed to set the site up and he is supposed to maintain it, and he will have to go to a lot more trouble to make changes to the navbar and stuff without SSI support and an ability to use php. I would definitely go the php route if it were available here.

This situation though got me thinking about whether there were any pure html/ccs only solution, which as I noted in my OP I already figured there wasn't.

Thanks for the responses.
