title: Can't reset CSS Appearance Property
body: <p>A site I'm working on has remove the drop down arrow from  boxes with:</p>
  
  <pre><code>select {
        -webkit-appearance: none;
      -moz-appearance: none;
      appearance: none;
  }
  </code></pre>
  
  <p>I need to add it back in, but nothing I've tried has worked so far</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>select {
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
  }
  select.diff {
    /* Aswell as normal, I have also tried revert &amp; unset */
    -webkit-appearance: normal;
    -moz-appearance: normal;
    appearance: normal;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;select&gt;

    &lt;option&gt;Automobiles&lt;/option&gt;
  &lt;/select&gt;
  &lt;select class="diff"&gt;
    &lt;option&gt;Oranges&lt;/option&gt;
    &lt;option&gt;Pears&lt;/option&gt;
    &lt;option&gt;Apple&lt;/option&gt;
