Remove margin from last item in row

Remove margin from last item in row you can use css nth-child

Here the example
ul li:nth-child(3n+3) {
color: #ccc;
}

From the script work for every third from the li

Or this for only one li

ul li:nth-child(5) {
color: #ccc;
}


From the script work only for fifth from the li

Good luck
