title: Fading in an answer after the submit button is clicked?
body: <p>How do I fad in an answer underneath a question after the submit button is clicked? For example I would like the correct answer to a question to appear only after the submit button is clicked.</p>
  
  <pre><code>&lt;p class="question"&gt;1.What is the capital of Greece?&lt;/p&gt;
  &lt;input id="q1a" type="radio" name="q1" value="a" /&gt;&lt;label for="q1a"&gt; Patras&lt;/label&gt;
  &lt;input id="q1b" type="radio" name="q1" value="b" /&gt;&lt;label for="q1b"&gt; Athens&lt;/label&gt;
  
  &lt;center&gt;&lt;input class="button" onclick="getResults()" type="submit" value="Submit" /&gt;
  
  
  &lt;strong&gt;Question 1:&lt;/strong&gt; The correct answer is Athens.
  </code></pre>
