title: Why width 960px?
body: <p>I have a question regarding fixed layout. It has two parts, closely related, so I'm putting in one question.</p>
  
  <p><strong>Part (a)</strong>
  Why 960px is suggested for the website layout? I understand that it is optimized for the most common screen resolution (1024px). But why exactly 960px? Won't the 1000px be as good?</p>
  
  <p><strong>Part (b)</strong>
  What exactly is Grid system? I did check 960.gs but didnt get the idea of columns. Is it better to use grid system (using the template from 960.gs, which looks so messy) or should i stick with traditional way, like:</p>
  
  <pre><code>&lt;div id="wrap"&gt;
       &lt;div id = "left-column"&gt;..&lt;/div&gt;
       &lt;div id = "center-column"&gt;..&lt;/div&gt; 
       &lt;div id = "right-column"&gt;..&lt;/div&gt;     
  &lt;/div&gt;
  </code></pre>
