我试图在动画结束时创建一个反弹效果,而不使用任何第三方代码或javascript。我不知道如何只使用纯CSS。
这是我到目前为止所做的:
HTML:
<div></div>
<div></div>
<div></div>
CSS:
div {
background: tomato;
width: 100px;
height: 100px;
margin-bottom: 10px;
transition: transform 0.3s ease-in;
transform-origin: top left;
}
div:hover {
-webkit-transform: scale3d(5, 5, 5);
transform: scale3d(5);
}

如果您只需要一次非常简单的反弹,就可以轻松将转换功能从ease-in
更改为其他内容,例如cubic-bezier
。
反弹的cubic-bezier
功能的示例是
cubic-bezier(0.175, 0.885, 0.32, 1.275)
一个完整的例子:
div {
background: tomato;
width: 100px;
height: 100px;
margin-bottom: 10px;
transition: transform 0.3s cubic-bezier(0.175, 0.885, 0.32, 1.275);
transform-origin: top left;
}
div:hover {
-webkit-transform: scale3d(5, 5, 5);
transform: scale3d(5);
}
<div></div>
<div></div>
<div></div>
您可以在easings.net找到其他一些缓和的例子,或在cubic-bezier.com找到一个完整的立方贝塞尔编辑器。

我是animate.css的粉丝

巧合的是,第一个动画是反弹的。
您可以从css文件中提取所需的代码。
使用animate.css框架我已经提取了他们的反弹动画,并在下面创建了一个片段:
@-webkit-keyframes bounce {
0%, 20%, 53%, 80%, 100% {
-webkit-transition-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
transition-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
-webkit-transform: translate3d(0,0,0);
transform: translate3d(0,0,0);
}
40%, 43% {
-webkit-transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
-webkit-transform: translate3d(0, -30px, 0);
transform: translate3d(0, -30px, 0);
}
70% {
-webkit-transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
-webkit-transform: translate3d(0, -15px, 0);
transform: translate3d(0, -15px, 0);
}
90% {
-webkit-transform: translate3d(0,-4px,0);
transform: translate3d(0,-4px,0);
}
}
@keyframes bounce {
