The grid system in Bootstrap is a series of columns, rows, and containers to accommodate the layout and align the content inside it. These are built in flexbox properties and are fully responsive across all your devices.

Let us understand with the help of an example:

<!doctype html>

<html lang='en'>

<head>

    <!-- Required meta tags -->

    <meta charset='utf-8'>

    <meta name='viewport' content='width=device-width, initial-scale=1'>

    <!-- Bootstrap CSS -->

    <link href='https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css' rel='stylesheet' integrity='sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC' crossorigin='anonymous'>

    <title>Hello, world!</title>

</head>

<body>

    <div class='container pt-4'>

        <div class='row'>

            <div class='col-sm bg-secondary text-light mx-1'>

                One of three columns

            </div>

            <div class='col-sm bg-secondary text-light mx-1'>

                One of three columns

            </div>

            <div class='col-sm bg-secondary text-light mx-1'>

                One of three columns

            </div>

        </div>

    </div>

    <!-- Optional JavaScript; choose one of the two! -->

    <!-- Option 1: Bootstrap Bundle with Popper -->

    <script src='https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js' integrity='sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM' crossorigin='anonymous'></script>

    <!-- Option 2: Separate Popper and Bootstrap JS -->

    <!--

    <script src='https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.2/dist/umd/popper.min.js' integrity='sha384-IQsoLXl5PILFhosVNubq5LC7Qb9DXgDA9i+tQ8Zj3iwWAwPtgFTxbJ8NT4GN1R8p' crossorigin='anonymous'></script>

    <script src='https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.min.js' integrity='sha384-cVKIPhGWiC2Al4u+LWgxfKTRIcfu0JTxR+EQDz/bgldoEyl4H0zUF0QKbrJ0EcQF' crossorigin='anonymous'></script>
