I don't know if this is possible or with what program. I am trying to design my site so that almost all changes are done using css or similiar.
What I would like to find is a way to set up all my main graphics on a similar setup so that when I change them I only have to change one page not every page on my site that uses the graphic. I hope this makes sense. Is this maybe better or possible with SSI, Any ideas?
With PHP, you would probably just split your site into a few sections, those that change and those that don't (change as in dynamic content). Then you just include the ones that don't change (typically a header and footer) in all your files.
