渲染CSS水平漸變

Question

我無法在本地工作： http://jsfiddle.net/efortis/t6QsP/ 我懷疑CSS或類似的陰影，因爲我看起來非常小心，它應該工作，它曾經工作，但由於許多更新我已經失去了窗口列表顏色的良好漸變功能。我的窗口現在看起來像這樣沒有梯度：

這是不是我，因爲我定義的HTML CSS類期待：

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

<table width="100%" border="1" cellspacing="0" cellpadding="2" align="center" class="horizontal-gradient">

     </div> 

我問過這件事，我們的結論是，這個問題是與我的其他代碼的東西： https://stackoverflow.com/questions/11344739/css-horizontal-gradient-not-working 所以我懷疑我是從某個地方遮蔽CSS類，這是我唯一的解釋。你有什麼想法如何解決這個問題？

鉻檢查元素表明，CSS被劃掉。這是什麼意思？

Answer 1

既然你提供的代碼工作正常，我能不能重現您的問題，這裏是你如何調試它：

1. 打開不正常的網頁在Chrome
2. 保持按Ctrl + Shift並按i - 開發人員工具將出現
3. 轉到「元素」選項卡
4. 按下窗口底部按鈕之間的放大鏡，然後單擊頁面上有問題的元素。在你的情況下，選擇應該有一個漸變的元素。
   或：使用「元素」選項卡中的DOM瀏覽器瀏覽您訪問元素的方式。
5. 選中元素後，檢查右欄中的「樣式」選項卡。所有樣式已應用到您的元素，按從上到下優先排序，這意味着如果已爲相同屬性定義了兩種樣式，則上面的樣式優先。

現在您可以看到您的樣式是否已被覆蓋到任何位置，以及樣式表和其中哪一行發生了。
