title: Making text block overlay cover the whole button
body: <p>I have the following code. Right now the overlay appears, but it's not on top of the image - it starts below the image. I want to make it that when I hover over the button, the info in the <code>&quot;wheel-display-overlay&quot;</code> class is visible and takes up the whole width and height of the button and is on top of the image.</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>button.wheel-display-button {
    background-color: white;
    background-size: cover;
    border-color: black;
    display: inline-block;
    height: 400px;
    padding: 0px;
    width: 20%;
  }
  
  button.wheel-display-button:hover .wheel-display-base {
    display: none;
  }
  
  button.wheel-display-button .wheel-display-overlay {
    display: none;
  }
  
  button.wheel-display-button:hover .wheel-display-overlay {
    background: black
    color: white;
    display: inline-block;
    position: relative;
    text-align: center;
    width: 100%;
    height: 100%;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;button class="wheel-display-button" 
          &lt;img src="variant.image"/&gt;

                  &lt;p&gt;Brand&lt;/p&gt;
          &lt;/span&gt;
