title: Button isn't clickable because of of a div overlay - possible z-index issue
body: <p>I have the following markup at the moment: <a href="https://jsfiddle.net/axgetf94/" rel="nofollow noreferrer">https://jsfiddle.net/axgetf94/</a></p>
  
  <p>I'm looking to build a responsive full screen video menu. Here's an image to what it looks like at the moment: <img src="https://i.imgur.com/OTuMSzE.jpg" alt="imgur"></p>
  
  <p>I'm talking about the bottom right tile. There are two icons, in an achor-tag which again are wrapped in a seperate div. My problem is, that one of those icons isn't clickable because of a div overlay. I thought that this might be solved by giving both the div's and the anchor tags a position and a z-index value.
  Unfortunately this doesn't solve my problem as the f-button is still not clickable.</p>
  
  <p>Here's my HTML:</p>
  
  <pre><code>&lt;div class="sm_tile sm_fb menu-item"&gt;
    &lt;div class="tcvpb_background_center"&gt;
      &lt;a href="http://facebook.com" title="fb"&gt;
        &lt;i class="fa fa-facebook"&gt;&lt;/i&gt;
      &lt;/a&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  &lt;div class="sm_tile sm_vm menu-item"&gt;
    &lt;div class="tcvpb_background_center"&gt;
      &lt;a href="http://vimeo.com" title="vm"&gt;
        &lt;i class="fa fa-vimeo"&gt;&lt;/i&gt;
      &lt;/a&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>After positioning my div's:</p>
  
  <pre><code>.tcvpb_background_center {
      left: 50%;
      position: absolute;
      text-align: center;
      width: 100%;
      z-index: 0;
  }
  
  .sm_vm .tcvpb_background_center {
      transform: translate(-65%);
  }
  .sm_fb .tcvpb_background_center {
      transform: translate(-35%);
  }
  </code></pre>
  
  <p>I give my links a pos: rel as well as a z-index of 1:</p>
  
  <pre><code>#menu-main-menu .menu-item .sm_tile a {
      border: 1px solid #fff;
      padding: 10px;
      position:relative;
      z-index: 1;
  }
  </code></pre>
  
  <p>The right button remains unclickable unfortunately and even though I looked into other z-index issues I can't seem  to resolve mine.
  Thanks in advance guys!</p>
