title: What does 0in mean as a unit of measurement?
body: <p>I'm going through the code on one of my school's canvas pages and I came across:</p>
  <pre><code>&lt;p style=&quot;margin: 0in; font-family: Calibri; font-size: 9.0pt;&quot;&gt;&amp;nbsp;&lt;/p&gt;
  &lt;p style=&quot;margin: 0in; font-family: Calibri; font-size: 9.0pt;&quot;&gt;&amp;nbsp;&lt;/p&gt;
  </code></pre>
  <p>Can someone explain what <code>0in</code> means? I can't find it on Google</p>
