Challenge: Use CSS Animation to Change the Hover State of a Button

Link to the challenge:

Hi

The instructions for this challenge show the following CSS @keyframes example for an animation with animation-name width:

@keyframes width {
    100% {
      width: 40px;
    }
  }

Try to use the same format as that example for your background-color @keyframes statement.
