我想要做的是在显示几个图像后,我想一个接一个地显示div中的内容.第一个div用1级然后是2然后3.我有上面的代码但不能正常工作.在stops中图像diplaying后我想只使用CSS而不是js或jquery

首先,你不能动画display属性,所以我建议使用opacity.

此外,类名不能以数字开头.

最后,要结束动画并保留最终属性,您必须使用animation-fill-mode.在这种情况下,值将是forwards.

html {
    -webkit-animation: chngepic 5s;
    /* Chrome, Safari, Opera */
    animation: chngepic 5s;
    background-repeat: no-repeat;
