title: Issues of padding-bottom when an element is below a div
body: <p>Heys guys. I've made a simple sample of a problem that has had me stumped for a long time - the code below has no purpose at all, it just shows the problem in a more legible way.</p>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
    &lt;head&gt;
      &lt;link rel="stylesheet" href="teste.css"&gt;
    &lt;/head&gt;
    &lt;body&gt;
      &lt;div id="bar"&gt;&lt;/div&gt;
      &lt;span&gt;
        Palavra       
      &lt;/span&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p><strong>CSS:</strong></p>
  
  <pre><code>#bar {
    position: relative;
    width: 100%;
    height: 7%;
    background-color: #5959AB;
    color: white;
    font-family: "Arial";
    font-size: 150%;
    font-weight: bold;
  }
  
  html, body {
    height: 100%;
  }
  </code></pre>
  
  <p>The result is:</p>
  
  <p><img src="https://i.stack.imgur.com/oLuGp.png" alt="enter image description here"></p>
  
  <p>So, I tried to make "Palavra" go up by adding a padding-bottom to it:</p>
  
  <pre><code>span {
    padding-bottom: 2000px;
  }
  </code></pre>
  
  <p>The result is:</p>
  
  <p><img src="https://i.stack.imgur.com/4wGwn.png" alt="enter image description here"></p>
  
  <p>"Palavra" just stays at the same precise position but a vertical scrolling bar appeared. It seems that "Palavra" is pushing down it's bottom part because it just can't go up from where it is.</p>
  
  <p>This problem is appearing for me in so many ways that my mind is already blowing - can someone please help?</p>
