title: Is it bad to put <div> elements within the <head> tags?
body: <p>I want to use conditional comments to make a DIV appear ONLY in browsers with IE7 or older, like this:</p>
  
  <pre><code>&lt;!--[if lt IE 7]&gt;
  
  &lt;div id="browsernotice"&gt;
  &lt;p&gt;You are using IE7 or less&lt;/p&gt;
  &lt;/div&gt;
  
  &lt;![endif]--&gt;
  </code></pre>
  
  <p>As far as I understand, conditional comments only work in the header.</p>
  
  <p>Is this bad?</p>
  
  <p>Should I rather use conditional comments to instert a stylesheet that makes an invisible DIV <code>visibility:visible</code>?</p>
