html - 渲染 CSS 水平渐变

Question

我无法在本地使用 fiddle : http://jsfiddle.net/efortis/t6QsP/而且我怀疑 CSS 或类似的阴影，因为我看起来非常仔细并且它应该工作，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漂亮渐变的功能。我的窗口现在看起来像没有渐变:

这不是我所期望的，因为我在 HTML 中定义了 CSS 类:

<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>
</table> 
        <table id="mainTable" border="0" class="tabell" cellspacing="5" cellpadding="2">
          <tr>
            <!-- Placeholder for the form table -->

我之前问过这个问题，我们得出的结论是问题出在我的其他代码上: https://stackoverflow.com/questions/11344739/css-horizontal-gradient-not-working所以我怀疑我从某个地方隐藏了 CSS 类，这是我唯一的解释。您知道如何解决这个问题吗？

这是整个 CSS 文件，我没有在其中找到阴影:

检查 chrome 中的元素显示 CSS 被划掉了。这是什么意思？

Answer 1

由于您提供的代码可以正常工作，我无法重现您的问题，因此您可以通过以下方式进行调试:

1. 在 Chrome 中打开功能失调的页面
2. 按住 Ctrl+Shift 并按 i - 将出现开发者工具
3. 转到“元素”选项卡
4. 按窗口底部按钮中的放大镜，然后单击页面上的相关元素。在您的情况下，选择应具有渐变的元素。
   或:使用“元素”选项卡中的 DOM 浏览器浏览相关元素。
5. 选择元素后，检查右栏中的“样式”选项卡。这里有已应用于您的元素的所有样式，按优先级从上到下排序，这意味着如果为同一属性定义了两种样式，则上面的样式优先。

现在您可以查看您的样式是否在任何地方被覆盖，以及它发生在哪个样式表和哪一行。
