How to achieve the progressive expansion of table row clicking! I once saw this effect on a flash RIA site, and the visual effect was really good. Flash developers also probably use this to demonstrate that the dynamic effect of flash applications is better than that of js (personal opinion ). Later, when I was doing bmail, I used GIF animation as the background and basically implemented this function, but I always felt that it was not perfect. In this case, the filter is used, which is visually smooth and saves the trouble of downloading images.
