JQuery Code

JQuery Code is given below. JQuery :nth-child() selector is used to select the alternate table rows.

The Jquery :nth-child(n) selector selects all elements that are the nth child of the parent element.

:nth-child(2n) will only select the alternate rows whose position is a multiple of 2.

Then css is applied to the selected rows using .css() method of JQuery.

<script>
$(document).ready(function(){
$("table tbody tr:nth-child(2n)").css('background-color','yellow');
});
</script>
