Easy Include
Use a simple javascript 'include' with a small .js file and add the same page elements to each page on your site, then just edit one file and all of your pages will show the new changes!
It's easy to do, just add your page elements to the .js file then use a special script call to pull the contents from the .js file and display them on your page. (The .js file must be uploaded to your webserver as well as your pages).
