title: How can I color specific letters in html element text?
body: <p>I have some <code>span</code> with some words in it, like</p>
  
  <pre><code>        &lt;span id="phrase"&gt;Here are some words&lt;/span&gt;
  </code></pre>
  
  <p>I need to color all the <code>'e'</code> characters red.</p>
  
  <p>I think of taking the <code>span.innerText property</code>, remove text node from span element and add some more spans inside (or instead), and give them necessary style.</p>
  
  <p>Is it the only way, or it could be solved in a more elegant way?</p>
