Question

因此，当页面加载时，我希望我的set容器能够反弹。例如，CSS应该是......

.bouncein {
  animation-name: bounceIn;
  animation-duration: 1s;
  animation-delay: 0.5s;`
}

但我需要知道关键帧。

因此，当页面加载时，我的div与类弹跳将会反弹。

Answer 1

你可以这样做：

.bouncein {
  animation-name: bounceIn;
  animation-duration: 1s;
  animation-delay: 0.5s;
  width: 100px;
  height: 100px;
  background-color: red;
}

@keyframes bounceIn {
0% {
	transform:translateY(-100%);
	opacity: 0;
}
15% {
  transform:translateY(0);
  padding-bottom: 5px;
}
30% {
  transform:translateY(-50%);
}
40% {
  	transform:translateY(0%);
    padding-bottom: 6px;
}
50% {
  transform:translateY(-30%);
}
}
70% {
    transform:translateY(0%);
    padding-bottom: 7px;
}
80% {
  transform:translateY(-15%);
}
90% {
  transform:translateY(0%);
  padding-bottom: 8px;
}
95% {
  transform:translateY(-7%);
}
97% {
  transform:translateY(0%);
  padding-bottom: 9px;
}
99% {
  transform:translateY(-3%);
}
100% {
  transform:translateY(0);
  padding-bottom: 9px;
  opacity: 1;
}
}

<div class="bouncein"></div>
