Question

这是一个非常令人沮丧的问题......我用CSS3制作了一个HTML5按钮 - 这个按钮在IE中工作（功能上），但是当我在Firefox（v 16.0.2）中打开我的页面时按钮不起作用（例如，你不能点击它 - 它什么都不做）。更奇怪的是，我把一个标准的href链接用于测试（在同一页面上，在按钮旁边），我甚至无法点击它（例如它什么都不做）。我已经在I.E 9和FireFox 16.0.2中的两台不同的机器上测试了这个页面。

以下是我的按钮的HTML代码：

<p><button type="button" onClick="location.href='index.php'" class="navigationButton">Back to World Map</button> 

<!-- test link -->
<a href="index.php">home</a></p>

CSS：

.navigationButton {
    font-family: Arial, Helvetica, sans-serif;
    font-size: 18px;
    color: #ffffff;
    padding: 10px 20px;
    background: -moz-linear-gradient(
        top,
        #86eb86 0%,
        #013006);
    background: -webkit-gradient(
        linear, left top, left bottom, 
        from(#86eb86),
        to(#013006));
    background: -ms-linear-gradient(#86eb86, #013006);
    background: -o-linear-gradient(#86eb86, #013006);
    background: linear-gradient(#86eb86, #013006);
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#86eb86', endColorstr='#013006');

    -moz-border-radius: 15px;
    -webkit-border-radius: 15px;
    border-radius: 15px;
    border: 3px solid #171717;
    -moz-box-shadow:
        0px 1px 3px rgba(000,000,000,0.5),
        inset 0px 0px 10px rgba(087,087,087,0.7);
    -webkit-box-shadow:
        0px 1px 3px rgba(000,000,000,0.5),
        inset 0px 0px 10px rgba(087,087,087,0.7);
    box-shadow:
        0px 1px 3px rgba(000,000,000,0.5),
        inset 0px 0px 10px rgba(087,087,087,0.7);
    text-shadow:
        0px -1px 0px rgba(000,000,000,0.4),
        0px 1px 0px rgba(255,255,255,0.3);
}

如果我对此按钮的实现适用于任何其他人（在I.E和Firefox中），请告诉我 - 否则如果我做错了，也请告诉我一个解释。

干杯！

修改这是其中一个页面的完整代码。它由PHP / MySQL动态生成......

Answer 1

事实证明，我的一个元素的z索引是个问题。在我的页面上，我的页脚div的z-index为20，上边距为500px，主内容区域的z-index值较低（按钮所在的位置）。由于边距区域“覆盖”按钮，我无法点击主要内容区域中的任何链接或按钮。

所以我已经解决了这个问题，虽然我仍然想知道为什么FireFox没有读取z-indexing和I.E呢 - 我使用Google的html5shiv来启用旧版本的I.E中的html5元素。

HTML5 <button>在Firefox中不起作用，但在I.E </button>中起作用
