title: What does the ? mean in an HTML absolute link
body: <p>I am learning HTML on my own, and I ran across the following external link that assigns a different font to a tag in CSS:</p>
  <pre><code>&lt;link href=&quot;https://fonts.googleapis.com/css?family=Lobster&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot;&gt;
  </code></pre>
  <p>I can't for the life of me find a definition of what the ? (question mark) does in this tag.  Could someone please address this?  Thanks in advance.</p>
