云的效果与太阳的实现方式是如出一辙,但是云是有多个的,而且是要不断的重复飘动,这里介绍新的动画参数
animation-iteration-count
动画播放次数,默认值为1,infinite为无限制,假如设置为无限制,那么动画就会不停地播放
元素的布局上,我都是保留的原尺寸,如果需要自适应,单独可以用百分比控制,通过background-size 一般可以设置 100% 100%的方式平铺元素,这样设置后图片就能自适应大小缩放了
打开index.html文件,在代码的53和57行填入相应代码,可以观察到小云的变化
0% { left: -5%; } 100% { left: 100%; }
