pShadow, short for ‘paper shadow’, is a jQuery extension that adds realistic drop shadows to HTML elements, which works in Internet Explorer (IE8, IE7, IE6 with some clever trickery), Firefox, Chrome, Safari, Opera, and any other modern browser you care to mention. It’s free to download and use, and you can see an example on the demo page.
We all know that modern browsers (apart from IE anyway) support the lovely CSS3 box-shadow property. But there are times when we need to cater for IE too, and sometimes a simple box-shadow just doesn’t cut the mustard. The pShadow jQuery extension does what all great performers do – it masters the art of illusion.
The shadow itself is actually a .png image, carefully designed to sit on the bottom edge of an element and give impression of depth and shadow, as if the element was a piece of paper sitting on your screen. No shadows are needed on the other edges, because the bottom shadow does all the work for you. Your eyes do the rest and turn it into a 3-dimensional object.
