Working with Pseudo-Classes

Question

This might be a stupid question but is it possible to color the second child in a pseudo class?

Answer 1

For this there is a pseudo-class nth-child(). In parentheses just written the number of the element you want to change

Answer 2

In the case of nth-child(), be sure to only put a number in the parentheses. Otherwise, it won't work. I have code up if you or anyone else wants to see it.
