If I want to change the content in the "page" section, but leave the title header and sidebar there, how would I do this? I can't imagine I have to have the header and sidebar on every page, or when I have to make a change to either of those, I have to change it on every page!

Any suggestions?

Thanks,
Dave


Use Server-Side Includes, e.g.:

<!--#include file="page.html" -->

Or:

<!--#include file="header.html" -->
<body>
 <h1>Title</h1>
 <p>...</p>
</body>
<!--#include file="footer.html" -->

i would suggest to iFrames

So should the code look something like this?

<html>
<head>
<title>EngineeringNotes.net</title>
<link href="style.css" rel="stylesheet" type="text/css" media="screen" />
</head>
<body>


<!--#include file="header.html" -->

<div class="page"><!-- start page -->

	<!--#include file="sidebar.html" -->

	
	<div class="content"><!-- start content -->

	</div><!-- end content -->
	
</div><!-- end page -->

</body></html>

With the header.html file as...

<div class="header">
	<div id="logo">
		<h1>EngineeringNotes.net</h1>
	</div>
	<div class="menu">
		<ul>
			<li><a href="mailto:daviddoria@gmail.com">Contact Me</a></li>
			<li><a href="phpBB3">Forums</a></li>
			<li><a href="Ideology.html">Ideology</a></li>
		</ul>
	</div><!-- end menu -->
</div><!-- end header -->

...and the sidebar.html file being...

<div class="sidebar"><!-- start sidebar -->
		<h2>EE Topics</h2> 
		<ul>
			<li><a href="Notes/EE/PatternRecognition.pdf">Pattern Recognition</a> </li>
			<li><a href="Notes/EE/ImageProcessing.pdf">Image Processing</a> </li>
			<li><a href="Notes/EE/ComputerVision.pdf">Computer Vision</a> </li>
			<li><a href="Notes/EE/ComputerGraphics.pdf">Computer Graphics (stub)</a> </li>
			<li><a href="Notes/EE/SignalsAndSystems.pdf">Signals and Systems</a> </li>
			<li><a href="Notes/EE/Communications.pdf">Communications</a> </li>
		</ul>
		

	</div><!-- end sidebar -->

OK...that worked on my server when I named the original document index.shtml. The shtml extention was required so that I could add the SSI (server side include) directives to the existing page.

Interesting, cool though - thanks all!
