CSS配合jquery制作完美漂亮的时钟，貌似在IE8下时钟不能获取时间啊！支持ie9、chrome、safari、firefox、opera （Chrome显示效果最佳，IE9下时钟无法工作）日历和骰子是原创，CSS3时钟并非原创但经过改良支持opera。数字日历的兼容性不错，圆形时钟就差点了，也希望一起交流，共同改进。(CSS with the jquery make perfect beautiful clock, seemingly in IE8 under the clock can not get the time ah! Support ie9, chrome, safari, firefox, opera (Chrome show the best results, the clock does not work under IE9) calendar and dice is original, CSS3 clock is not original but after improved support opera. Digital calendar compatibility is good, almost round the clock on, and also hope together, and work together to improve.)
