title: How to change HTML span title font size?
body: <p>Im trying to change font size of span title element. I was googling for good example, and I have found this one: <a href="http://jsfiddle.net/tDQWN/" rel="nofollow noreferrer">link</a></p>
  
  <p>But even if title is being shown inside gray tooltip, the second one appears: 
  <a href="https://i.stack.imgur.com/IcMXw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IcMXw.png" alt="enter image description here"></a></p>
  
  <p>My question is: how to style this second one tooltip (yellow one) by increasing its font size?</p>
  
  <p>My span looks like this:</p>
  
  <pre><code>&lt;span title=${code} &gt;&lt;/span&gt;
  </code></pre>
