我需要你的帮助。

我的子子菜单似乎与子菜单重叠，这很好，但我想将它向右推几下，以免子菜单文本被切断。

这是正在发生的事情的图片：

在此处输入图像描述

这是我的 HTML 和 CSS 标记：

调整您的代码以匹配以下内容。工作样本：http ://codepen.io/BJack/full/Cflem

<li> 的宽度是 150px，所以绝对定位时将 left 属性偏移 150px。

li:hover .sub-level {
    background: #999;
    border: #fff solid;
    border-width: 1px;
    display: block;
    position: absolute;
    left: 150px;
    top: 0px;
}

.sub-level li:hover .sub-level {
  display:block;
  position: absolute;
  left: 150px;
}

你可以尝试添加这个

li:hover .sub-level li:hover .sub-level { 
    left: 175px;
}
