CSS CSS Foundations Advanced Selectors Pseudo-Classes: :nth-child

nth-last-child

could someone please explain me how nth-last-child should be used. in this video he uses nth-last-child(-n +3) and for some reason the last 3 list items are selected. shouldn't it be like 3 represents the 8th list item and then coz its -n it should go one above till the first list item?

what you are saying is nth-child(-n+8), 8 list item is selected and it will work his way back to the 1st list item. Now the nth-last-child does the same, but it starts at the 10th list item, sort of the first item for that selector. Making the n negative (-n) it will fill the list items towards the first list item (in the case of the nth-last-child: list item 10) I tried to make it a little more visible down below.

nth-child(-n+3) 1 2 3 4 5 6 7 8 9 10

1 2 3 4 5 6 7 8 9 10 nth-last-child(-n+3)

Hope I made some sense on my first answer :)

thanks a lot for the help and not bad for your first answer :)
