div height not increasing to surround child content

I created an input field in a div

The div height is auto but unfortunately the searchbar_home div height is not increasing to surround my input box and submit button.

Here's my HTML

  <div id='container'>    
    <div id="content">
        <h1 class="home_title">English to Malayalam</h1>
        <div id="searchbar_home">
            <input type="text" />
            <input type="submit" />
        <p>Copy right only for me ;)</p>



    margin: 0 auto 20px;
    padding: 10px;
    height: auto;
    width: 80%;
    background: #F5F5F5;
    border: 1px solid #D8D8D8;

    border-radius: 6px;
    clear: both;
#searchbar_home input[type="text"]{
    height: 35px;
    float: left;
    width: 90%;
    border: 1px solid #CCCCCC;
    border-right: none;

    border-radius: 6px 0 0 6px;
#searchbar_home input[type="submit"]{
    float: left;
    background: #414141;
    height: 40px;
    width: 50px;

Here is the demo on jsfiddle.

How do I get the `searchbar_home``div' to increase in size?


Ah you've tried to use the :after trick for clearing your floats?

From your code:

         clear: both;

You'll need to actually give it some content and make it a block item rather than inline -

         clear: both;

Should work.

I assume you've floated your input. To make the div size to fit it, add an overflow:auto; rule to it's style.
