CSS CSS Foundations Selectors Basic Structural Pseudo-Classes

Why do we say "first-child" of the li, and not the ul?

The code challenge says: "Select the li that is the first child of the ul. Set the color to white and background color to black."

and this is the right answer

li:first-child {
  color: white;
  background-color: black;
}

But logically shouldn't it be a ul instead of li? I mean, we are trying to target the first child of the ul. I'm confused.

Good question. It is a child to parent relationship. Meaning first-child pseudo class targeting element from child perspective.

li:first-child{


}

The above CSS code snippet selects li element that is first child to its parent.

See! it is a whole way of seeing child - parent relationship.

I hope I answered your question.

Because first-child will be selecting every "li" element that is the first-child of its parent.
