Hi please look at the HTML below. I am trying to use jQuery to get every 3rd instance on the DIVs with class=\"box\" contained within the DIV with class=\
class=\"box\"
class=\
Your :nth-child selector does not reference n, and you need to reference the inner div in your selector.
n
div
Try:
$(document).ready(function(){ $("div.entry div:nth-child(3n)").css("margin", "0px"); });
