渲染CSS水平渐变

Question

我无法在本地工作： http://jsfiddle.net/efortis/t6QsP/ 我怀疑CSS或类似的阴影，因为我看起来非常小心，它应该工作，它曾经工作，但由于许多更新我已经失去了窗口列表颜色的良好渐变功能。我的窗口现在看起来像这样没有梯度：

这是不是我，因为我定义的HTML CSS类期待：

<div class="popup" id="popupD" 
      style="display: none;" > 

<table width="100%" border="1" cellspacing="0" cellpadding="2" align="center" class="horizontal-gradient"> 
    <tr> 
    <td colspan="3"><h2><div class="horizontal-gradient">Pandora sök</div></h2> 
</td> 
    <td><a href="javascript:void(0)" onclick="document.getElementById('popupD').style.display = 'none';">X</a></td> 
</tr>

我问过这件事，我们的结论是，这个问题是与我的其他代码的东西： https://stackoverflow.com/questions/11344739/css-horizontal-gradient-not-working 所以我怀疑我是从某个地方遮蔽CSS类，这是我唯一的解释。你有什么想法如何解决这个问题？

铬检查元素表明，CSS被划掉。这是什么意思？

Answer 1

既然你提供的代码工作正常，我能不能重现您的问题，这里是你如何调试它：

1. 打开不正常的网页在Chrome
2. 保持按Ctrl + Shift并按i - 开发人员工具将出现
3. 转到“元素”选项卡
4. 按下窗口底部按钮之间的放大镜，然后单击页面上有问题的元素。在你的情况下，选择应该有一个渐变的元素。
   或：使用“元素”选项卡中的DOM浏览器浏览您访问元素的方式。
5. 选中元素后，检查右栏中的“样式”选项卡。所有样式已应用到您的元素，按从上到下优先排序，这意味着如果已为相同属性定义了两种样式，则上面的样式优先。

现在您可以看到您的样式是否已被覆盖到任何位置，以及样式表和其中哪一行发生了。
