Why doesn't my course accept my border properties of none?

.main-nav:li:first-child { border: none; border-top-left-radius: 5px; border-top-right-radius: 5px; }

Hey Chris,

I think the problem is that you're trying to select a pseudo-class called "li". If you want to select the first list item inside of the element with the main-nav class you should write it with a space instead of a colon between .main-nav and li like so:

.main-nav li:first-child { 
  border: none; 
  border-top-left-radius: 5px;  
  border-top-right-radius: 5px; 
}

I hope that helps! :)

Ahhh that was it. Thank you sir!
