<h2>Hoverable Links</h2>
When you mouse over the links inside the nav, their background color will change to grey by default.
If you want a different background color on hover, use any of the w3-hover-color classes, and if you want a different text color on hover, use any of the
w3-hover-text-color classes.

Hover background color:
<ul class="w3-navbar w3-border w3-light-grey">
 <li><a class="w3-hover-red" href="#">Home</a></li>
 <li><a class="w3-hover-blue" href="#">Link 1</a></li>
 <li><a class="w3-hover-green" href="#">Link 2</a></li>
 <li><a class="w3-hover-teal" href="#">Link 3</a></li>
</ul>

Hover text color (You can turn off the default hover effect with the w3-hover-none class. This is often used when you only want to highlight text color (and not background color) on hover):
<ul class="w3-navbar w3-black">
 <li><a class="w3-hover-none w3-text-white" href="#">Home</a></li>
 <li><a class="w3-hover-none w3-text-grey w3-hover-text-white" href="#">Link 1</a></li>
 <li><a class="w3-hover-none w3-text-grey w3-hover-text-white" href="#">Link 2</a></li>
 <li><a class="w3-hover-none w3-text-grey w3-hover-text-white" href="#">Link 3</a></li>
</ul>
