title: Links not working inside div
body: <p>I think this question is related to <a href="https://stackoverflow.com/questions/16382431/link-not-working-inside-floated-div">Link not working inside floated div</a> but I still can't figure it out. </p>
  
  <p>I have a div as follows: </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>.fullwidthimage {
    width: 100%;
    position: relative;
    z-index: -1;
  }
  .imageoverlay {
    left: 0;
    text-align: center;
    position: absolute;
    z-index: 1;
    top: 15px;
    width: 100%;
  }
  #homepagebutton {
    position: absolute;
    text-align: center;
    z-index: 100;
    bottom: 50px;
    width: 200px;
    height: 60px;
    left: 50%;
    margin-left: -100px;
    font-size: 25px;
    border: 1px solid black;
    border-radius: 5px;
    background-color: orange;
    color: black;
    text-decoration: none;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="fullwidthimage"&gt;
    &lt;img class="noround imageundertext smallimg" src="http://placehold.it/600x800"&gt;
    &lt;img class="noround imageundertext midimg" src="http://placehold.it/1000x1000"&gt;
    &lt;img class="noround imageundertext bigimg" src="http://placehold.it/3200x1300"&gt;
    &lt;img class="noround imageundertext xlimg" src="http://placehold.it/5000x1500"&gt;
    &lt;h1 class="imageoverlay"&gt;Title Here&lt;/h1&gt;
    &lt;a href="#getstarted" id="homepagebutton"&gt;Get Started&lt;/a&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>The different images are using a CSS media query to display/hide at different sizes. The whole thing is a full width image with a text title and 'button' (that's actually just a link styled to look like a button) over the top of the image. </p>
  
  <p>Whatever links I put inside that div won't work - the text shows on the page, but nothing happens if you mouse over. </p>
  
  <p>Why?! </p>
  
  <p>Links placed immediately outside of the div on the same page work just fine, so I don't think it's anything to do with other containing divs there. </p>
  
  <p>I'm assuming from that previous question asked that it's something to do with the positioning, but I can't make it work. </p>
  
  <p>Thanks!</p>
