General assembly-lesson 5 checkpoint 16 (defining a keyframe)

I’m extremely green with coding and I’m currently on project 5 checkpoint 16, the project is asking me to define a keyframe to make the robots eyes blink but I don’t know what im doing wrong with my syntax.

@keyframes blink {50% {
background: radial-gradiant(circle, red 15%, transparent 40%), #cc5;}

this is the current syntax I have written down but apparently its not correct, any help of guidance is much appreciated

>Solution :

You are missing a closing } and you miss-spelled gradient as gradiant. Other than that, you’re fine.

div {
  width: 100px;
  height: 100px;
  animation: blink 5s infinite;
}

@keyframes blink {
  50% {
    background: radial-gradient(circle, red 15%, transparent 40%), #cc5;
  }
}

<div></div>
