Can anybody suggest structure alternatives to frames and iframes? I like being able to edit the overall look of my website by editing a single page and without having to edit individual pages, but I'm sick of frames/iframes. My server is not PHP nor ASP enabled. (Not that I know how to use those anyway. . . ) Thanks for any suggestions!

do you have SSI? You could use server side includes then [.shtml files]

Thanks for the suggestion... I tried to enable SSI on my server by adding the SSI info to the .htaccess file but it still won't work. Does that means it's useless and SSI won't work on my server, or can I try something else to enable it?

Also, are there any other suggestions of alternatives to frames out there besides SSI in case it can't work? Thanks!

There is always Front Page Themes....

Edit a shared border that is applied to all pages.

Have you tried Search & Replace?
