title: Underline span but not p
body: <p>I have an span that contains a p-tag and text. Now I want to add an underline effect on hover. But I only want to underline the Text, in this case 'Tree', but not the 'Test'. Unfortunately I can not add anything to the 'tree'. I can not remove the underlining in the p-tag with text-decoration: none.</p>
  <pre><code>&lt;span id=&quot;underline&quot;&gt;
    &lt;p id=&quot;noUnderline&quot;&gt;Test&lt;/p&gt;
    Tree
  &lt;/span&gt;
  </code></pre>
  <p>Any ideas?</p>
