实现代码
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
width: 100%;
height: auto;
background: #f90;
overflow: hidden;
}
.box {
width: 50px;
height: 50px;
background: #f70;
transform: rotate(45deg);
position: absolute;
box-shadow: 2px 2px 3px rgba(0, 0, 0, 0.3);
}
.box1 {
left: calc(50% – 25px);
top: calc(100% – 75px);
animation: box1 cubic-bezier(1, 0, 0.45, 1.4) 2s 1;
}
.box2 {
left: calc(50% – 65px);
top: calc(100% – 115px);
animation: box2 cubic-bezier(1, 0, 0.45, 1.4) 2.5s 1;
