If you are looking for a solution for a progress bar, I direct you to the following resources: Bare Naked App provides a simple and elegant solution based on pure CSS with two images. You control the percentage of completion through the background-position attribute of the CSS. HTML: <img src="/images/percentImage.png" alt="... CSS: img.percentImage { background: white url(/imag... Images: (percentImage.png) (percentImage_back.png) WebAppers extended the above solution with JavaScript.
