Hi Josue! If you combine the selectors you have to target the first-child li in .main-nav and change the top-left and bottom-left border-radius to 5px it comes out like so:

.main-nav, li:first-child {
  border: none;
  border-radius: 5px 0 0 5px;
}

Hope this helps!

You have to select the list items in the .main-nav and give it the pseudo element :first-child.

.main-nav li:first-child {
  border-style: none;
  border-radius: 5px 0 0 5px;
}

Remember border-radius can take 4 values. taking the example above 5px is border top left, 0 is the border top right, the second zero is border bottom right, then the last 5px is border bottom left. Think of a clock going clockwise. -Hope this helped you Josue.

You need to be more specific with your selector for this particular question. They are looking for " border-top-left-radius" and "border-bottom-left-radius" I believe.
