Question

我正在尝试在z轴上排列元素并想要订购它们。正如您在示例中所看到的，第二部分看起来好像是在第一个元素（粉红色背景）之上，但在z轴（-2500px）上具有较低的值。我错过了什么？

html,
body {
    margin: 0;
    padding: 0;
    height: 100%;
    overflow: hidden;
}

#content,
#wrapper  {
    position: absolute;
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    overflow: hidden;
}

#wrapper {
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
}

#content {
    -moz-perspective: 10000px;
    -ms-perspective: 10000px;
    -webkit-perspective: 10000px;
    perspective: 10000px;

    -webkit-transform: translate3d(0, 0, 0) perspective(10000px);
    transform: translate3d(0, 0, 0) perspective(10000px);

section.fullscreen {

    bottom: 0;
    left: 0;
    top: 0;
    height: 100%;
    width: 100%;
}

section:nth-of-type(2) {
    color: red;
    background: black;
}

第二个元素显示为偏移1500px，但这就是3D变换所做的全部。要真正把它放在第一部分的“后面”并隐藏它，你需要使用z-index：

section:nth-of-type(1) { z-index: 2; }
section:nth-of-type(2) { z-index: 1; }

请参阅JSFiddle。
