Challenge: Practice Structural Pseudo-Classes

Task

We are working with a set of elements, and the goal is to practice applying different colors using structural pseudo-classes. Your task is as follows:

• Apply the color red to the first element using a structural pseudo-class.
• Apply the color blue to the last element using a structural pseudo-class.
• Apply the color green to every second element using a structural pseudo-class.

• :first-child: Targets the first child of a parent element.
• :last-child: Targets the last child of a parent element.
• :nth-child(): Targets a specific child of a parent element based on its position in the list. For instance, to select every second list item (2, 4, 6, etc.), you can use :nth-child(2n).
