in the code of your main site page. copy everything from the
<div id="header">
to the closing
</div><!-- #header (end) -->
and put it in your overall_header.html file right after the opening
<body>
tag.
you will need to add the stylesheet link from the main site to the overall_header file in the head section.
you may have to do some tweaking of the css if there are any duplicate css tags.
remember, you must download the files to your computer to edit them with a real text editor.
Dreamweaver and Frontpage are not good choices when it comes to file editors (
find out why). Use a simple text editor such as
Notepad++ with an FTP client such as
FileZilla
also, after every change you must refresh your template from the admin panel/styles section in order to see the changes.
luck,
