title: How to control position and colour of title text in HTML href element?
body: <p>Using HTML and CSS, but not JS, how can I alter the position, text colour and background colour of the title text that shows when a link is hovered over? I would like to centre the title text below the midpoint of the link text.</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-css lang-css prettyprint-override"><code>a:link {text-decoration: none;
  color: #000;
  border-bottom: 2px solid #f00;  }
  
  a:hover, a:active
  {text-decoration: none;
  color: #f00;
  border-bottom: 2px solid #f00;  }
  
  a:visited {text-decoration: none;
  color: black;
  border-bottom: 2px solid #888;  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div&gt;
  &lt;a href="#" title="hello"&gt;text&lt;/a&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
