我无法弄清楚这段代码中的错误在哪里。我正在尝试使用以下 css 将背景颜色更改为任何颜色:

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

但是除了出于某种原因将导航栏向下移动几行之外,它没有改变任何东西。为什么会发生这种情况,为什么我不能更改背景颜色?

最佳答案

像下面这样更改 css 链接顺序

<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/

在同一个选择器中,main.css 将覆盖 bootstrap.min.css
