title: pause youtube video and show div with a form
body: <p>I have a youtube video on my website:</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-html lang-html prettyprint-override"><code>&lt;div id="video"&gt;
    &lt;iframe width="560" height="315" src="https://www.youtube.com/embed/some_video" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt; 
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>after some fixed time, I want to pause it and ask the user a question by overlaying a form over the video:</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-html lang-html prettyprint-override"><code>&lt;h1&gt;how do you like the video so far? &lt;/h1&gt;
  &lt;div id="question"&gt;
    &lt;form&gt; 
      &lt;input type="radio" name="question" value="poor" checked&gt;Poor&lt;br&gt; 
      &lt;input type="radio" name="question" value="good"&gt;Good&lt;br&gt; 
      &lt;input type="submit" value="Submit"&gt; 
    &lt;/form&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>What would be the javascript code to pause the video after a fixed period of time and what would be the css for displaying the form nicely? Basically I want to mimic the way lectures on <a href="http://coursera.org" rel="nofollow noreferrer">coursera.org</a> once looked like.  </p>
