Adding classes to LI with JQuery LI to every 7th item

javascript, jquery

Solution

Try:

$('ul li:nth-child(7n+1)').addClass("first");

This will select every 7th element.

See demo on jsFiddle.

Problem

I am using this code to add a class to every 7th LI items and the first one too: ``` $('ul li:first, ul li:nth-child(7n)').addClass("first"); $('ul li:first, ul li:nth-child(1)').addClass("first"); ``` My problem is that it just adds the class to the 1st and the 7th item but if I add another 7 or more it doesn't add it. I need to add the class the every 7th li item.
