I very much disagree with the following two points: On Jun 21, 10:51 pm, "howard chen" <[EMAIL PROTECTED]> wrote: > 2. Put rollover stuffs into CSS is no good: CSS for layout & design, > JS for effect > 1. CSS can't preload image, the plugin can
2. This is a subject that's certainly debatable, so I won't fault you for opting to use JavaScript to handle this effect. However, I personally think rollovers ARE part of the design. They certainly do have a certain amount of "behaviour" to them, but CSS offers a simpler and more lightweight way of achieving this effect, and it works if JavaScript is unavailable. But that's simply my opinion. 1. This is the more important thing I wanted to comment on. While it IS true that CSS rollovers are NOT preloaded if you swap out an image on hover, you can get around this quite elegantly if you use a different approach: use a single image and simply shift the background- position. Two well-known pieces on the subject: http://www.alistapart.com/articles/sprites/ http://www.wellstyled.com/css-nopreload-rollovers.html I hope anyone reading this makes an informed decision about choosing how to tackle this problem. JavaScript isn't the only option.
