• There's some issue but adding one more example can help,
  p:nth-last-child(3) selects the third-to-last <p> element within its parent.'

• a warning can also be added so case syntax error

Also here the problem/question here is staged for :Nth Type Selector

Nth-of-Type Selector

Select an element based on its occurrence among siblings of the same type.

:nth-of-type(A)

Targets elements of the same type by their position within a parent, counting from the start. Similar to :nth-child, but it only considers siblings of the same type, not all child elements.

Example
p:nth-of-type(3)
This selects the third <p> element within its parent.
