这是我的代码:
<head>
<style type="text/css">
#cssmenu > ul li {
background-color: #F4F4F4;
display: block;
position: relative;
text-decoration:none;
}
#cssmenu > ul li a {
background-color: #F4F4F4;
display: block;
position: relative;
margin: 0;
border-bottom: 1px dotted #d9d9d9;
border-left: 1px dotted #D9D9D9;
border-right: 1px dotted #D9D9D9;
padding: 15px 10px;
width: 150px;
font-size: 11px;
text-decoration:none;
color:#7C7C7C;
}
#cssmenu > ul li a:hover {
background-color:#4285F4;
color:white;
}
#header_content {
height:25px;
width:60%;
color:White;
background-color:#083061;
margin-left:320px;
}
</style>
</head>
<body>
<div style="width:100%">
<div id='cssmenu' style="width:10%;margin-top:1px;">
<ul style="margin-top:0px;margin-left:30px;">
<li><a href='#'><span>DASHBOARD</span></a></li>
<li><a href='#'><span>RESOURCES</span></a></li>
<li><a href='#'><span>CALL ROUTING</span></a></li>
<li><a href='#'><span>RECORDINGS & CALL LOGS</span></a></li>
</ul>
</div>
<div id="header_content">
<label>Dashboard</label>
</div>
</body>
我想水平修复这两个div?
