  <p>I was looking through the source of <a href="https://github.com/murtaugh/HTML5-Reset" rel="noreferrer">HTML5 Reset</a> when I noticed the <a href="https://github.com/murtaugh/HTML5-Reset/blob/master/index.html#L113" rel="noreferrer">following line</a>:</p>
  
  <pre><code>&lt;script src="//ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Why does the URL start with two forward slashes? Is this a shorthand for <code>http://</code>?</p>
