Solution

So now look at the Solution and how we are going to achieve this.

HTML

</div>

CSS

  height: 300px;
  background: #5d3a3a;
}

After applying the CSS to .box it will look like this:

.box div {
  background: #b5e0ba;
  width: 200px;
  height: 200px;
}

  width: 200px;
  height: 200px;
  background: #b5e0ba;
}
