title: What is the difference between applying css rules to html compared to body?
body: <p>I don't see the difference between:</p>
  
  <pre><code>html {
      background: #f1f1f1;
  }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>body {
      background: #f1f1f1;
  }
  </code></pre>
  
  <p>Any explanation?</p>
