This JavaScript simply displays a Windows-XP style progress bar on your page. The bar doesn't really do anything other than give your visitor something to look at while the page loads.

This JavaScript shows a progress bar used as a timer. You set the total time for delay. Then set the bar width, height, and colors in the .js code part and the bar "counts" up the amount of time you specified. Note: the script starts only once the page is fully loaded.
