HTML结构

示例中，我们使用Bootstrap布局，该css3鼠标经过动画特效的HTML结构如下：

<div class="container">
    <div class="row">
        <div class="col-md-4 col-sm-6">
            <div class="box">
                <img src="/images/img-1.jpg">
                <ul class="icon">
                    <li><a href="https://zhishitu.com"><i class="fa fa-search"></i></a></li>
                    <li><a href="https://zhishitu.com"><i class="fa fa-link"></i></a></li>
                </ul>
                <div class="box-content">
                    <h3 class="title">Williamson</h3>
                    <span class="post">Web Developer</span>

                </ul>
                <div class="box-content">
                    <h3 class="title">Kristiana</h3>

CSS样式

然后通过下面的CSS样式来实现该css3鼠标经过动画特效。
