Issue
I have these nested divs and I need the main container to expand (in height) to accommodate the DIVs inside
<!-- 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 is this:
* {
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;
}
The problem I have is that #main_content doesn't stretch to accommodate all the inner divs, with the result that they keep going against the background.
How can I solve this problem considering the above scenario?
Solution
You need to force a clear:both before the #main_content div is closed. I would probably move the <br class="clear" />; into the #main_content div and set the CSS to be:
.clear { clear: both; }
Update: This question still gets a fair amount of traffic, so I wanted to update the answer with a modern alternative using a new layout mode in CSS3 called Flexible boxes or Flexbox:
body {
margin: 0;
}
.flex-container {
display: flex;
flex-direction: column;
min-height: 100vh;
}
header {
background-color: #3F51B5;
color: #fff;
}
section.content {
flex: 1;
}
footer {
background-color: #FFC107;
color: #333;
}<div class="flex-container">
<header>
<h1>
Header
</h1>
</header>
<section class="content">
Content
</section>
<footer>
<h4>
Footer
</h4>
</footer>
</div>Most modern browsers currently support Flexbox and viewport units, but if you have to maintain support for older browsers, make sure to check compatibility for the specific browser version.
