 <pre><code>&lt;div id = "container"&gt; &lt;div id="header"&gt;&lt;/div&gt; &lt;div id="content"&gt;&lt;/div&gt; &lt;div id="footer"&gt;&lt;/div&gt; &lt;/div&gt; #container {min-width:620px;} </code></pre> <p>See example: <a href="http://jsfiddle.net/calder12/xN2PV/3/" rel="nofollow">http://jsfiddle.net/calder12/xN2PV/3/</a></p> <p>Point to note. min-width is not supported in IE6. I doubt this matters, if it does you'll need a different solution.</p>
