每个人，

我第一次使用 box-shadow 创建了一个汉堡图标，但由于某种原因，只有顶部栏是一个超链接：http: //jsfiddle.net/vq5r0r8j。

标记：<a href="#menu" class="box-shadow-menu"></a>

CSS：

.box-shadow-menu {
    position: relative;
}

.box-shadow-menu:before {
    content: "";
    position: absolute;
    top: 10px;
    width: 35px;
    height: 4px;
        background: white;
    box-shadow: 0 10px 0 0 white, 0 20px 0 0 white;
}

任何解决此问题的帮助将不胜感激。

谢谢！
