You could always do what's known as "content wrapping".
Uses technology called PHP. At a very simple level, all you do is make one file for the top half of each page (for example, the headers and site links) and one for the bottom of each page (copyright and contact details for example).
Then you just make separate pages for the bits in between and have a little script that sticks them all together and puts them on the screen for the visitors.
Benefits of all this is, saves time in the long run as once you've converted the pages once, no need to do it again as if or when you decide to change the layout/colours/design, just alter the wrappers and everything else will take care of itself.
Something like this:
Open a new file in Notepad, save it as index.php and put this in it:
<h3>This is the main content of your page</h3>
<p>If you right click me and choose View Source, you'll see that I've stuck three bits of HTML together to make a web page!</p>
Now make another file called header.inc and put this in it:
<title>Test Page Type Thing</title>
Finally, make another file called footer.inc and put this in it:
Upload all three files to a folder on the server, ensure that they're all in the same folder together and then go to that page on the server.
That's all there is to it. Can be made as simple or as complicated as you like. This is very simple PHP page, but it can get a lot more complicated.
