2 Navigation - " Please set the padding-top to 14px" - What have I done wrong?


#1

I keep getting the error message " Please set padding-top to 14px" as far as I can see I have, someone suggested I change my CSS code as follows;
li{
padding-bottom: 14px;
padding-left:10px;
padding-right:10px;
padding-top:14px;
}
.nav a {
color: #5a5a5a;
font-size: 11px;
font-weight: bold;
text-transform: uppercase;
}

This still hasn't worked. This is my code:

  <div class="container">
    <ul>
      <li><a href="#">Airbnb logo</a></li>
      <li><a href="#">Browse</a></li>
    </ul>
    <ul>
      <li><a href="#">Sign Up</a></li>
      <li><a href="#">Log In</a></li>
      <li><a href="#">Help</a></li>
    </ul>
  </div>
</div>

<div class="jumbotron">
  <div class="container">
    <h1>Find a place to stay.</h1>
    <p>Rent from people in over 34,000 cities and 192 countries.</p>
  </div>
</div> 

<div class="learn-more">

    </div>
  </div>
</div>

You have a missing DIV-pairing

  <div class="container">
    <ul>
      <li><a href="#">Airbnb logo</a></li>
      <li><a href="#">Browse</a></li>
    </ul>
    <ul>
      <li><a href="#">Sign Up</a></li>
      <li><a href="#">Log In</a></li>
      <li><a href="#">Help</a></li>
    </ul>
