CSS3制作秒表

CSS3制作秒表效果,以前想都不敢想,但thecodeplayer.com却完美的使用了CSS3中的animation属性制作了一个纯CSS3的秒表计时器的效果,让我们想都不敢想象,曾经需要javaScript的效果,如今使用CSS3的几个属性就完成了。在这个效果中主要是控制时间数字的显示,本例中每个数定的宽度和高度都定死了,其动画实现主要逻辑是通过对数字进行绝对定位,依靠改变数字的“top”属性值来实现时间数字的变更,当关还需要大家计算好他们之间转换的速率。所以说这个例子绝对是一个练习CSS3的animation属性的好例子,你要是掌握了这个例子,我想你对animation会有一个质的认识,希望大家喜欢(^_^)。

1、动画的逻辑就是给数字使用了绝对定位,改变“top”的属性值;
2、分 和 秒 应该是 '60' 而不是 '100',因此需要创建两个动画;
3、十步十个数字
4、六步六个数字
