title: Why does margin 0 on the body not remove the margin on an h1 element?
body: <p>As far as I know body should target all elements nested inside it. In my case it should give my h1 a margin of 0;</p>
  
  <pre><code>   body {
     font: 15px/1.5 Arial, Helvetica, sans-serif;
     padding: 0;
     margin: 0;
     background-color: #f4f4f4;
  </code></pre>
  
  <p>}</p>
