How do I add the hover I looked it up on other places and when I put it in it still refused to accept it.

Hello John, the hover effect will work as follow:

a {
  color: green;
  background-color: red;
}

a:hover {
 color: grey;
background-color: blue;
}

Basically what happens is that when you hover on top of the "a" element the color of the text will change to green from grey and the color of the background will change from red to blue.

The first segment of code determines the actual colors and the ":hover" selector will determine what will happen once you hover with your mouse on top of it. now that could apply to anything not just color changes! So it could become very very interesting! I suggest that you keep studying this because you'll end up having lots of fun with it :)

Hope that helped :)

Anytime, and Mark thanks for your help with the code challenge question. Next time when you answer a question try not to give the whole answer but instead try to educate the students and help them understand what they are doing and what the challenge really wants them to learn. Its very important that students will learn WHY things work the way they do and not just HOW they work.
