Common Header / Footer with static HTML

Is there a decent way with static HTML/XHTML to create common header/footer files to be displayed on each page of a site? I know you can obviously do this with PHP or server side directives, but is there any way of doing this with absolutely no dependencies on the server stitching everything together for you?

Edit: All very good answers and was what I expected. HTML is static, period. No real way to change that without something running server side or client side. I've found that Server Side Includes seem to be my best option as they are very simple and don't require scripting.

There are three ways to do what you want

Server Script

This includes something like php, asp, jsp.... But you said no to that

Server Side Includes

Your server is serving up the pages so why not take advantage of the built in server side includes? Each server has its own way to do this, take advantage of it.

Client Side Include

This solutions has you calling back to the server after page has already been loaded on the client.

JQuery load() function can use for including common header and footer. Code should be like

<script>
    $("#header").load("header.html");
    $("#footer").load("footer.html");
</script>

You can find demo here

Since HTML does not have an "include" directive, I can think only of three workarounds

1. Frames
2. Javascript
3. CSS

A little comment on each of the methods.

Frames can be either standard frames or iFrames. Either way, you will have to specify a fixed height for them, so this might not be the solution you are looking for.

Javascript is a pretty broad subject and there probably exist many ways how one might use it to achieve the desired effect. Off the top of my head however I can think of two ways:

1. Full-blown AJAX request, which requests the header/footer and then places them in the right place of the page;
2. <script type="text/javascript" src="header.js"> which has something like this in it: document.write('My header goes here');

Doing it via CSS would be really an abuse. CSS has the content property which allows you to insert some HTML content, although it's not really intended to be used like this. Also I'm not sure about browser support for this construct.

You can do it with javascript, and I don't think it needs to be that fancy.

If you have a header.js file and a footer.js.

Then the contents of header.js could be something like

document.write("<div class='header'>header content</div> etc...")

Remember to escape any nested quote characters in the string you are writing. You could then call that from your static templates with

<script type="text/javascript" src="header.js"></script>

and similarly for the footer.js.

Note: I am not recommending this solution - it's a hack and has a number of drawbacks (poor for SEO and usability just for starters) - but it does meet the requirements of the questioner.
