我试着用z-index，但它不起作用！

还有别的办法吗？

<div class="flex w-full p-20">
    <div class="w-full">
        <div class="flex mx-auto w-8 h-8 bg-gray-300 rounded-full"></div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="flex mx-auto w-8 h-8 bg-blue-300 rounded-full"></div>
            <div class="absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-green-500"></div>
            </div>
        </div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="mx-auto w-8 h-8 bg-blue-500 rounded-full"></div>
            <div class="absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-gray-700"></div>
            </div>
        </div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="mx-auto w-8 h-8 bg-green-500 rounded-full"></div>
            <div class="absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-red-500"></div>
            </div>

如果您通过类将静态位置重置为相对位置，则可以在回合中触发Z索引：relative z-10。

​

<link href="https://cdnjs.cloudflare.com/ajax/libs/tailwindcss/2.2.19/tailwind.min.css" rel="stylesheet"/>
<div class="flex w-full p-20">
    <div class="w-full">
        <div class="flex mx-auto w-8 h-8 bg-gray-300 rounded-full relative z-10"></div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="flex mx-auto w-8 h-8 bg-blue-300 rounded-full relative z-10"></div>
            <div class="absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-green-500"></div>
            </div>
        </div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="mx-auto w-8 h-8 bg-blue-500 rounded-full relative z-10"></div>
            <div class="absolute inset-0 flex items-center -translate-x-2/4 ">
                <div class="h-0.5 w-full bg-gray-700"></div>
            </div>
        </div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="mx-auto w-8 h-8 bg-green-500 rounded-full relative z-10"></div>
            <div class="absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-red-500"></div>
            </div>
        </div>
    </div>
</div>

你需要把负z索引设置到条形图上。

若要设置负z索引，请检查https://tailwindcss.com/docs/z-index#negative-values上的文档。

添加了负的z-索引设置后，代码应该如下所示：

<div class="flex w-full p-20">
    <div class="w-full">
        <div class="flex mx-auto w-8 h-8 bg-gray-300 rounded-full"></div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="flex mx-auto w-8 h-8 bg-blue-300 rounded-full"></div>
            <div class="-z-10 absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-green-500"></div>
            </div>
        </div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="mx-auto w-8 h-8 bg-blue-500 rounded-full"></div>
            <div class="-z-10 absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-gray-700"></div>
            </div>
        </div>
    </div>

    <div class="w-full">
        <div class="relative">
            <div class="mx-auto w-8 h-8 bg-green-500 rounded-full"></div>
            <div class="-z-10 absolute inset-0 flex items-center -translate-x-2/4">
                <div class="h-0.5 w-full bg-red-500"></div>
            </div>
        </div>
    </div>
</div>

我试着用css做了，结果是：

.container {
    width: 100px;
    height: 100px;
    background: red;
    z-index: 9999;
}

.bar {
    background: blue;
    width: 200px;
    height: 10px;
    position: fixed;
    margin-top: 50px;
    margin-left: 80px;
    z-index: -1;
}  

Html：

<div class="bar"></div>
<div class="container"></div>
