这是我的 HTML 结构：

<div class="pageSlider">
    <a href="#lounge" class="active">Visitor's Lounge</a>
    <a href="#streams">News Stream</a>
    <a class="slide-button"></a>
</div>

这是我的 CSS 规则：

.pageSlider {
    margin: 15px auto !important;
    font-size: 1.2em;
    white-space: nowrap;
    height: 35px;
}
.pageSlider a[href] {
    display: inline-block;
    text-align: center;
    text-decoration: none;

    z-index: 2;
}
.pageSlider a[href].active {
    color: #000;
}
.pageSlider .slide-button {
    background-color: #cccc00;
    position: relative;
    top: -35px;
    display: inline-block;
    height: 35px;
    padding: 0;
    float: left;
    height: inherit;

    z-index: 1;
}

.pageSlider .slide-button设置为z-index: 1并.pageSlider a[href]设置为z-index: 2，但较低的 z-index 实际上与较高的重叠。

我不知何故需要.slide-button得到链接下的链接，但我似乎找不到更好的方法。

您忘记添加：

position:relative;

在您的链接 ( .pageSlider a[href]) 上。z-index仅适用于定位元素。
