Html CSS bounceInDown效果不起作用

我试图达到一种“反弹内陷”的效果，就像，但什么也没发生。你知道怎么了吗？参见JSFIDLE：

HTML:

---

您必须添加两个类。

animated

类将项目指定为动画项目。然后单击

bounceInDown

，以定义动画的类型

<div id="box" class="animated bounceInDown">test</div>

测试

以下是一个简单的解决方案：

首先创建一个css类

myAnimation

。 然后在HTML中使用它：

.myAnimation{
-webkit动画：弹跳输入1秒，轻松输入输出200秒；
动画：弹跳下降1秒，缓慢下降200秒；
}

使用animate.css制作动画

#box {
    position: absolute;
    top: 317px;
    left: 295px;
    padding: 20px 20px 20px 55px;
    text-decoration: none;
    background:#0F6
}
