title: Retrieve letter position on hover
body: <p>Every letter doesn't have it's own wrapper element, everything is inside paragraph.</p>
  
  <p>And I am wondering if I can retrieve the position of the letter in string when I hover over it's parent element?</p>
  
  <p>For example: <code>&lt;p&gt;The quick brown fox jumps over the lazy dog&lt;/p&gt;</code> has <code>innerText.length = 43</code>, if I hover over <code>f</code>, it should return <code>16</code>.</p>
  
  <p>Any way to do this?</p>
  
  <p>Thanks in advance!</p>
