HTML

<div id="textwidth">This goes with the text</div>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<div id="autowidth">This is auto</div>
This is outside the div boundaries and therefore bad.

CSS

#textwidth{
    float: left;
    color: white;
    background: blue;
    padding: 5px;
}

#autowidth{
    background: red;
    color: black;    
}
