I'm guessing this is an easy one, I hope so:
I've done many sites over the years, using Dreamweaver as my main program. Done them in HTML, and many with PHP.
Recently, I've really liked using PHP includes for my navigation bars, headers and footer. I like this rather than using Templates within Dreamweaver.
I now have a client, that for SEO reasons, will not let my use PHP, they strictly want HTML, XHTML or CSS.
Within that, how can I use common elements like a footer or header throughout, without having it actually coded onto each page?
