title: specified body CSS width is safe?
body: <p>Now very often content with a certain size centered.</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
    &lt;style type="text/css"&gt;
      #content { margin: auto; width: 960px;}
    &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
     &lt;div id="content"&gt;Blah!&lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Is it safe to not use a wrapper for alignment and size, and apply it directly to a <code>body</code> tag? <strong>Like this</strong>: </p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
     &lt;style type="text/css"&gt;
        body { margin: auto; width: 960px;}
     &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
     Blah
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
