          As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of <a href="#mink">mink</a>, <a href="#bears">bears</a>, and <a href="#eagles">bald eagles</a>.

Hi Jonathan,

try:

.wildlife {
  background-image: url('img/bear.jpg');
  background-repeat: no-repeat;
  background-position: center;
  background-size: cover;
  box-sizing: border-box;
}

What is box-sizing: border-box?

Well basically normally when you adding padding/borders to your elements it will increase the width and height of that element.

For e.g.

If you have a div that is 300px wide and you add padding-right 20px you have 300 + 20px = 320px. The div is 320px wide.

But if you add box-sizing: border-box to your CSS the width doesn't change but you still get the padding you were looking for.

I personally add box-sizing: border-box to all my elements. Like this:

* {
box-sizing: border-box;
}
