Question

我有这个HTML和CSS并且在chrome / firefox中运行良好但是在IE上标题布局已经过了并且悬停时没有显示子菜单，请你帮忙：

<html>
    <head>
    <title>title</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <meta name="viewport" content="width=1024" />
    <meta name="description" content="" />
    <meta name="robots" content="all" />
    <link href="images/favicon.ico" type="image/x-icon" rel="icon" /><link href="images/favicon.ico" type="image/x-icon" rel="shortcut icon" />     
    <link rel="stylesheet" type="text/css" href="css/style.css" />

    </head>

    <body>
     <div id="page">
        <div id="header">
            <div class="content">
                <div id="logo">
                    <a href="/"><img src="images/logo.gif" title="" alt="" /></a>
                </div>

                <div class='cssmenu'>
                    <ul>
                       <li class='active'><a href='index.html'><span>Home</span></a></li>
                       <li><a href='#'><span>Products</span></a>
                          <ul>
                             <li><a href='#'><span>Product 1</span></a></li>
                             <li><a href='#'><span>Product 2</span></a></li>
                          </ul>
                       </li>
                       <li><a href='#'><span>About</span></a></li>
                       <li><a href='#'><span>Contact</span></a></li>
                           <li><a href='#'><span>About</span></a></li>
                       <li><a href='#'><span>Contact</span></a></li>
                       <li><a href='#'><span>Contact</span></a></li>
                    </ul>
                </div>

            </div>
        </div>

        <div id="sub_header">
            <div class="content">
                <div class="content_l">
                    <span id="sub_head_title">Welcome</span>
                </div>
                <div class="content_r">
                    <span>
                    Call
                    <strong>000000000000</strong>
                    </span>
                </div>
            </div>
        </div>
       </div>   
    </body>

</html>

而css是：

* html .clearfix, 
* html #main_panel {
  height: 1%;
  overflow: hidden;
}

/* float clearing for IE7 */
*+html .clearfix {
  min-height: 1%;
}

/* float clearing for everyone else */
.clearfix:after {
  clear: both;
  content: ".";
  display: block;
  height: 0;
  visibility: hidden;
  font-size: 0;
}

html, body { 
background: #e5e5e5; 
font-size: 13px; 
}

#header { 
    background: transparent url(../images/header-bg.jpg) repeat-x; height: 60px;
}

#header .content, #sub_header .content { 
overflow: visible; position: relative; 
}

#header .content, #sub_header .content {
    overflow: visible;
    position: relative;
}

div.content {
    margin: 0 auto;
    overflow: hidden;
    width: 980px;
}

#logo { 
position: absolute; 
}

#logo { margin: 8px 0 8px 0; }
#logo a { border: none; }

#page #sub_header {
    margin-bottom: 0;
}

#sub_header {
    line-height: 49px;
}

#sub_header {
    background: none repeat scroll 0 0 #EEEEEE;
    border-bottom: 1px solid #DDDDDD;
    margin-bottom: 30px;
    overflow: hidden;
}

.content_l {
    float: left;
    overflow: hidden;
    width: 50%;
}

.content_r {
    float: right;
    text-align: right;
    width: 50%;
}

#sub_header span {
    color: #2D2D2D;
    line-height: 49px;
}

#sub_head_title {
    font: bold 21px Arial;
    text-shadow: 2px 2px 2px #FFFFFF;
}

a.header_button_children span {
    background: url("../images/header-children-off.gif") no-repeat scroll right -51px transparent;
    padding-right: 25px;
}
a.header_button span {
    height: 19px;
    padding: 8px 10px 3px;
}

Answer 1

它与我合作，但似乎缺少DOCTYPE所以你的浏览器午餐Quirks模式，所以添加

<!DOCTYPE html>

在<html>标记之前阻止IE浏览器切换到Quirks模式。

css适用于Firefox / Chrome但不适用于IE
