In the past, I have always used PHP for even my basic site design stuff, and I have never used the .html extension. Several reasons for doing this, but one of the biggest ones was being able to use "PHP Includes" on my site, so I would only have to design my navigation once. 

This worked fine, because Dreamweaver was always able to render basic PHP stuff that was not really "Server-side", like the includes. But now, I am trying to switch to using Adobe Edge Code, because it is truly lightweight and I don't have to load up a big application on slower computers to do work. It is also really nice, because it does have great CSS editing, and a wonderful live preview that just works in browser. From what I have found out, their is no way of doing the cooler stuff, when you are using .php files. 

So - I guess my question is, Is it possible to do something like "PHP-Includes" only using HTML/CSS/JS? Or do I really need to stop being lazy and switch my workflow back to doing all HTML, and just Copy/Paste the nav sections on each page.

Also - sorry if this question is to much like a "Discussion", I tried to write it as straight forward as I could. 

Edit: The application supports JavaScript, CSS, and HTML and, one of my friends is recommending jQuery. Anyone know how it would work with jQuery? Or if it would?
