Zebra Stripping is the technique of having different colours per each line on a list. It generally is considered to help users read large tables of information; however there is evidence suggesting the effectiveness of zebra stripes is somewhat overrated. Having said that, in CSS3 it’s very easy to implement so it’s worthwhile adding.
To add Zebra Strips to a list, all you need to do is adding the following pseudo-class to the end of the CSS element you wish to edit:
ul#example_list li:nth-child(odd) {
background-color:#FFF;
}
