Create star images where the inside of the star is transparent and its border is solid/opaque/black. Fill the negative space (image area outside the star) with white (or whatever matches the background color/pattern of the area the stars will populate on the webpage). Now, since you know the width of each star image, you can calculate how many pixels match a particular rating. For instance, say you have 5 stars lined up, each 100px wide -- If the rating is 50% (2.5 of 5 stars) the "pixel percentage" would be 250px. You can then fill the background of the div containing the stars with a contrasting color proportionally to the "pixel percentage". I'd likely use a fixed height div with the calculated 250px width & a z-index just below the star images to accomplish this for a 50% rating. The result would show the leftmost 2 stars filled in with the contrasting color, the 3rd star half way filled, and the last two "empty". This method is "cooler" than the commonly known CSS method as it supports higher visual accuracy (for instance 3/100 of a star can be filled). ~ Brice _______________________________________________ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
