Design a Set of Colored Boxes Step 10

I cannot finish this for the life of me. I ran the code through the validator, and it came back fine.

<body>
<div class="color-grid">
    <div class="color-box color1"></div>
    <div class="color-box color2"></div>
    <div class="color-box color3"></div>
    <div class="color-box color4"></div>
    <div class="color-box color5"></div>
</div>
</body>
</html>
body{

  background-color: #f4f4f4;

}

.color-box{

width: 20px;

height:20px;

}

.color1{

background-color: #ff0000

}




.color2{

background-color: rgb(125, 20, 50);

}




.color3{

background-color: orange;

}




.color4{

background-color: hsl(240, 100%, 50%);

}




color5{

background-color: purple;

}

Is this a class selector?

Yeah, oops. Thanks for pointing this out!
