Need help here

It tells me to adjust the border radius when there isn't any border. Additionally, when I do, it just tells me to set all border properties to none.

style.css
/* Complete the challenge by writing CSS below */
.main-nav:first-child > li:first-child {
    border: none;
  border-radius: 5px 0px 0px 5px;
}

I think you missed a small detail on what the question was asking:

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

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

You were selecting the wrong elements. Does that help?

your code as you wrote it

/* Complete the challenge by writing CSS below */
.main-nav:first-child > li:first-child {
    border: none;
  border-radius: 5px 0px 0px 5px;
}

you've made this more complicated than it needs to be

by trying to use the ">" to target a direct child descendant. In this use case if you look at the index.html file its not necessary or the simplest way to deal with this.

simply using:

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

you have already selected " .main-nav " and its descendant " li " all you needed to complete it was to say you want the first child of this list.

your final code would then look like this

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