title: Change details of the tag inside the tag with jQuery
body: <p>I hope that I can explain my question clearly.</p>
  
  <pre><code>&lt;button type="button" class="" id="myId"&gt;
  &lt;p style="color: red;"&gt;hello&lt;/p&gt;
  &lt;/button&gt;
  </code></pre>
  
  <p>How to change the attribute <code>style</code> of the tag <code>&lt;p style="color: red;"&gt;hello&lt;/p&gt;</code> if I only know that this tag is in the <code>&lt;button&gt;</code> tag with id <code>"myId"</code> using <code>jquery</code>?</p>
