无法找到覆盖网页上输入字段的元素

标签： html css css3

我对css有点新意，让浏览器在布局上合作对我来说有点困难。我得到了一种我认为有效的格式，但当我将它用于联系表单时，我意识到某些内容覆盖了我的输入字段，因此我无法在其中输入文本，但我无法弄清楚是什么。 This is a JSfiddle with all of my html and css欢迎提出任何建议。

HTML：

<body>
    <div class="header">
            <h1>MultiDimensional Imaging<br>
            <span class="catchphrase">Give better ultrasound service, make thousands more.</span></h1>
        <p class="stamp">OB/GYNS ONLY</p>
    </div>
    <div class="nav">
        <ul class="menu">

2 个答案:

答案 0 :(得分：4)

z-index的{​​{1}}为负数，导致它位于stack的底部。您可以position to the <body>and give it a z-index value >= 0或者您可以将.content的{​​{1}}更改为＆gt; = 0，然后只需给z-index和.content更高的值：< / p> 

.nav

答案 1 :(得分：2)

这是因为你在content类上放了一个负索引，所以它落后于所有其他元素（以及它内部的输入）。重新排序z索引，以使content类不在任何与输入字段重叠的其他元素之后。
