Use the CSS ":nth-child" selector

You can use the CSS3 :nth-child selector to highlight the background of alternate table row for creating a zebra-striped table. The :nth-child(N) pseudo-class accepts an argument N, which can be a keyword, a number, or a number expression of the form xn+y where x and y are integers (e.g. 1n, 2n, 3n, 2n+1, 3n-2, …). Try out the following example to see how it works:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Highlighting Alternate Table Row Using CSS</title>
<style>
    table{
        margin: 30px;
        border-collapse: collapse;
    }
    table tr{
        border-bottom: 1px solid #666;
    }
    table tr:nth-child(2n){
        background: #f2f2f2;
    }
    table th, table td{
        padding: 10px;
    }
</style>
</head>
<body>
    <table>
        <tr>
            <th>Row</th>
            <th>First Name</th>
            <th>Last Name</th>
            <th>Email</th>
        </tr>
        <tr>
            <td>1</td>
            <td>John</td>
            <td>Carter</td>
            <td>johncarter@mail.com</td>
        </tr>
        <tr>
            <td>2</td>
            <td>Peter</td>
            <td>Parker</td>
            <td>peterparker@mail.com</td>
        </tr>
        <tr>
            <td>3</td>
            <td>John</td>
            <td>Rambo</td>
            <td>johnrambo@mail.com</td>
        </tr>
        <tr>
            <td>4</td>
            <td>Harry</td>
            <td>Potter</td>
            <td>harrypotter@mail.com</td>
        </tr>
    </table>
</body>
</html>

output:

Row First Name Last Name Email
1 John Carter johncarter@mail.com
2 Peter Parker peterparker@mail.com
3 John Rambo johnrambo@mail.com
4 Harry Potter harrypotter@mail.com
