Make div's height expand with its content

Question

Make div's height expand with its content

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?

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>

add the following:

overflow:hidden;

height:1%;

to your main div. Eliminates the need for the extra <br /> for the clear.
