我有这些嵌套的div，我需要主容器扩展(在高度)，以适应内部的div
<!-- head -->
...
<!-- /head -->
<body class="main">
<div id="container">
<div id="header">
<!--series of divs in here, graphic banner etc. -->
</div>
<div id="main_content"> <!-- this DIV _should_ stretch to accommodate inner divs -->
<div id="items_list" class="items_list ui-sortable">
<div id="item_35" class="item_details">
</div>
<div id="item_36" class="item_details">
</div>
<div id="item_37" class="item_details">
</div>
<!-- this list of DIVs "item_xx" goes on for a while
each one representing a photo with name, caption etcetc -->
</div>
</div>
<br class="clear"/>
<div id="footer">
</div>
</body>
</html>
CSS是这样的:
* {
padding: 0;
margin: 0;
}
.main {
font: 100% Verdana, Arial, Helvetica, sans-serif;
background: #4c5462;
margin: 0;
padding: 0;
text-align: center;
color: #000000;
}
.main #container {
height: auto;
width: 46em;
background: #4c5462;
margin: 0 auto;
border: 0px solid #000000;
text-align: left;
}
.main #main_content {
padding: 5px;
margin: 0px;
}
#items_list {
width: 400px;
float: left;
}
.items_list {
width: 400px;
float: left;
}
.item_details {
margin-top: 3px;
margin-bottom: 3px;
padding: 3px;
float: left;
border-bottom: 0.5px solid blue;
}
我的问题是，#main_content没有拉伸以适应所有的内部div，其结果是它们一直在与背景相反。
考虑到上述情况，我该如何解决这个问题?
