Please i need help with how to Use CSS Animation to Change the Hover State of a Button

Tell us what’s happening:

Your code so far


<style>
  button {
    border-radius: 5px;
    color: white;
    background-color: #0F5897;
    padding: 5px 10px 8px 10px;
  }
  
  button:hover {
    animation-name: background-color;
    animation-duration: 500ms;
  }
  @keyframes {
   100% {background-color:#4791d0;}
  }
  
  
</style>
  
<button>Register</button>

instead of that first line @keyframes { use this instead:

@keyframes background-color {

@keyframes background-color {
   100% {background-color:#4791d0;}
  }
