With each new page I have to update the navigation panel. Which means I go from page to page copying and pasting my navigation bar. The more pages I add the harder it gets.
If your page is strictly HTML then you will just have to do copy and paste. It would have been a lot better if you were using may be PHP then you can simply do an include or require but as the situation is now, all you need is to do a clean HTML coding for your navigation. Indent your codes well then it will be easier for you to copy and page across all pages.
If you can use simple PHP codes then read this: http://www.w3schools.com/php/php_includes.asp
