CSS: Layering icons on top of image/video div on hover
<p>I render a div with an image that looks like it's a video (but it's just an image, for performance). When the user clicks on the image, JS swaps out the image with the appropriate youtube embed code and plays the video.</p>

<p>Below the image/video div, I have another div with some action icons (share, like etc). Rather than have the actions below the image/video div, I'd like to put them over the image/video div on:hover. See below image for better description:</p>

<p><a href="https://i.stack.imgur.com/cb0wk.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cb0wk.jpg" alt="enter image description here"></a></p>

<p>Here's the current structure of my code.</p>

<p>The HTML:</p>

<pre><code>&lt;div class="youtube-container col-sm-6 col-lg-4"&gt;
  &lt;div class="youtube-player"  data-id="&lt;%= trailer.youtube_id %&gt;"&gt;
      &lt;div class="holder"&gt;
      &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;div class="row icons"&gt;
  &lt;div class="icon"&gt;
    &lt;img src="icon1"&gt;
  &lt;/div&gt;

  &lt;div class="icon"&gt;
    &lt;img src="icon2"&gt;
  &lt;/div&gt;

  &lt;div class="icon"&gt;
    &lt;img src="icon3"&gt;
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>CSS:</p>

<pre><code>  .icons img {
    height: 35px;
    margin: -10px 0 0 5px;
  }

   .icons {
    float:left;
    margin: 30px 10px 10px 10px;
  }

.icon img {
  height: 55px;
}

.youtube-container {
    display: block;
    margin: 20px auto;
    width: 100%;
    width: 100%;
}

.youtube-player {
    display: block; width: 100%; /* assuming that the video has a 16:9 ratio */
    padding-bottom: 56.25%;
    overflow: hidden;
    position: relative;
    width: 100%;
    height: 100%;
    cursor: hand;
    cursor: pointer;
    display: block;
}

img.youtube-thumb {
    bottom: 0;
    display: block;
    left: 0;
    margin: auto;
    max-width: 100%;
    width: 100%;
    position: absolute;
    right: 0;
    top: 0;
    height: auto
}

div.play-button {
  height: 72px;
  width: 72px;
  left: 50%;
  top: 50%;
  margin-left: -36px;
  margin-top: -36px;
  position: absolute;
  background: url("http://i.imgur.com/TxzC70f.png") no-repeat;
}


#youtube-iframe {   &lt;--- the iframe dynamically generated when someone clicks the image
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
}
</code></pre>

<p>After the page is loaded, Javascript goes through and 1) finds all the .holder divs 2) inserts a dynamically generated image 3) Adds an on.click event listener to .holder that, when clicked, swaps the image for a youtube iframe.</p>

<p>I understand how to implement the "on hover" part, by I need help with CSS and overlaying the icons on top of the image/video. </p>
