这是一款CSS3鼠标hover图片光芒四射动画特效。该特效中，当鼠标Hover图片的时候，通过对伪元素添加渐变和clip-path，来制作光芒四射的效果，非常炫酷。

HTML结构
该特效中图片和它的容器的基本HTML结构如下：

<div class="box">
    <img src="images/img-1.jpg">
    <div class="box-content">
        <div class="inner-content">
            <h3 class="title">孙悟空</h3>
            <span class="post">七龙珠</span>
        </div>
        <ul class="icon">
            <li><a href="#"><i class="fa fa-search"></i></a></li>
            <li><a href="#"><i class="fa fa-link"></i></a></li>
        </ul>
    </div>
</div>
