title: Covering full header with background image
body: <p>In my header, I'm trying to get my background image to cover my full header but nothing I'm doing seems to be fixing it.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.header {
    background-image: url("https://iso.500px.com/wp-content/uploads/2015/12/stock-photo-125301449-1500x822.jpg");
    background-postion: center center;
    background-size: cover;
    height: 100%;
    width: 100%;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="header"&gt;
    &lt;div id="header-text"&gt;
      &lt;h1&gt;Olivia Cahill&lt;/h1&gt;
      &lt;h2&gt;A Collection of Her Art&lt;/h2&gt;   
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Edit:
  When i say cover, I mean that I want the whole first top part of the page to have the image</p>
