Question

出于某种原因我的css根本不想工作。 DIV只是不想按照我声明它们的方式对齐。如果显示某些文本，它基本上只是环绕文本。它根本不像普通的css文件一样调整页面。

我的css如下所示：

body {
height: 95%;
width:100%;
margin:0 auto;}

#HEADER{
height: 15%;
width: 100%;
border-bottom: 2px solid black;}

#CONTAINER{height:85%;}

#CONTENT{
height:100%;
border-left: 2px solid black;
}

CSS应该控制以下div

<body>
<div id="HEADER">
    TITLE HERE
</div>
<div id="CONTAINER">
    <div id="MENU">

    </div>

    <div id="CONTENT">
        <asp:ContentPlaceHolder ID="CPH_Content" runat="server">

        </asp:ContentPlaceHolder>
    </div>
    <div id="FOOTER">

    </div>
</div>

我已经在头部宣布了我的css，如下所示：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Labo 2</title>
<link href="/CSS/main.css" rel="stylesheet" type="text/css"/>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>

我也尝试过 href =“〜/ CSS / main.css”而没有任何运气。

据我所知，外部页面没有任何形状或形式的安全保护，但为了确保我在web.config中声明了以下内容以确保它是可访问的

 <location path="CSS">
  <system.web>
    <authorization>
      <allow users="*"/>
    </authorization>
  </system.web>
</location>

任何人都可以给我一些帮助或一些急需的解释，我称之为的任何JavaScript都像魅力一样，只有css才真正让我感到厌烦。

谢谢！

好吧，我已经找到了问题

为了让％值启动，我必须声明html标记，而不仅仅是css文件中的body标记。

现在一切都很完美！谢谢你的帮助！

像这样：
