<div class="nav">

<div class="jumbotron">
<div class="container">

It keeps getting this: . Add an h3 element in the third supporting content div. But the third content div clearly has the <h3>element with the Trust and Safety. Help please

@ximperiah,
You have to return to the drawing board....

Your un-ordered-list Element should be part of <div class="nav"> </div>
like

<div class="nav"> 
  <!-- with a container-div ??? -->
    <ul>
      <li>Ximperiah</li>
      <li>Browse</li>
      <li>Sign Up</li>
      <li>Log In</li>
      <li>Help</li>
    </ul>
   <!-- /div closing the container-div -->
 </div> <!-- closing the nav div -->
