背景顏色不會更改錯誤

我找不出錯誤代碼在哪裏。我嘗試使用以下css來改變背景顏色到任何東西：背景顏色不會更改錯誤

body { 
background-color: black; 
    padding: 0px; 
    margin:0px; 
    height: 1500px; 
}

但除了換擋導航欄下幾行出於某種原因它不改變任何東西。爲什麼會發生這種情況，爲什麼我不能更改背景顏色？

的index.html

試用背景：＃000000; – 2014-12-11 03:13:23

嘗試'背景顏色：黑色！重要;'有什麼東西在壓倒它。 – JunM 2014-12-11 03:13:34

該代碼似乎對我工作正常。 http://jsfiddle.net/kkyo5pgu/無法複製該問題。 – 2014-12-11 03:15:08

更改CSS鏈接順序如下圖所示

<link href="css/bootstrap.min.css" rel="stylesheet"> 
<link rel="stylesheet" type="text/css" href="main.css">

工作正常http://jsfiddle.net/gtpco6k9/

在同一個選擇

，main.css將覆蓋bootstrap.min.css

有關CSS的優先順序，看看這篇文章 - >here
