title: HTML and BODY Tags are not at 100% Width/Height
body: <p>I'm making a website and the "<code>html</code>" and "<code>body</code>" tags are not filling up the entire page. 
  <hr>
  <strong>Question</strong>: Is it suppose to do that? <br>
  It doesn't have any <code>css</code>, yet it still does that. I thought it was at 100% width/height at default. I do have pretty bad memory though. <br><br>
  <strong>Here's the code</strong>: </p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
      &lt;head&gt;
          &lt;title&gt;Test Site&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;p&gt;Hello! &lt;/p&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Since I don't have a <code>REPUTATION</code> of <strong>TEN</strong> to post images, <br>
  here's the link to the image: 
  <code><a href="https://lh4.googleusercontent.com/j0DgeD1gRgfOdAGQkiR5vKgKoYxnlLosmecjibixqXGb9xhwJl4IHEUbA-8TcLBmhUZRaIBEhFFswRw=w1368-h635-rw" rel="nofollow noreferrer">https://lh4.googleusercontent.com/j0DgeD1gRgfOdAGQkiR5vKgKoYxnlLosmecjibixqXGb9xhwJl4IHEUbA-8TcLBmhUZRaIBEhFFswRw=w1368-h635-rw</a></code>

  Please help, I need to make this for a project soon. </p>
