about link but left: -50%; doesn't quite do it for me, is this because the container is absolutely positioned in relation to the nav link therefore only moving it to the left half of the nav link? If this is the case would a transform be better?position: absolute;, does an absolutely positioned element in relation to another absolutely positioned element set the first element absolute to the second? it seems to work here but i'm not sure if that's good practice or is valid?
