Hey there Japneet,

You've pretty much got it, with one exception. You have a space between the colon (:) and nth-child. With pseudo-selectors, you can't have a space, or the browser won't know to read that as being 'attached' to the element. Just remove the space and you're good to go. :)

:dizzy:

You need to remove the space between I and nth-child.

li:nth-child(4n)
