title: Putting border around header
body: <p>I'm trying to put a border around a header, nothing seems to be working... apologies, I'm pretty new to all of this, so is there another way?</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 {
    margin-left: auto;
    margin-right: auto;
    margin-bottom: 10px;
    width: 852px;
    height: 179px;
    border: 10px #FFFFFF;
    border-radius: 6px;
    background-image: url("https://upload.wikimedia.org/wikipedia/commons/thumb/a/aa/Vincent_van_Gogh_-_Self-portrait_with_grey_felt_hat_-_Google_Art_Project.jpg/250px-Vincent_van_Gogh_-_Self-portrait_with_grey_felt_hat_-_Google_Art_Project.jpg");
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;header&gt;
