Rows

A row is used to define a selection of elements that should be dealt with as a horizontal group. As such, rows reside within a container element. The power of the row lies in being able to stack content vertically, almost like containers within a container, or defining a section of the page. Creating a row is as simple as applying the row class to the desired element:

<body>
    <div class="container">
        <h1>Help, I'm trapped in a container!</h1>
        <div class="row">
            <div>Section 1</div>
        </div>
        <div class="row">
            <div>Section 2</div>
        </div>
        <div class="row">
            <div>Section 3</div>
        </div>
    </div>
    <div>
        <h1>I'm free!</h1>
    </div>
</body>

Take a look at Figure 2.4, as follows:

The true power of rows only becomes apparent when they are used with columns.

Flexbox is now on by default, so support for IE9 was dropped from Bootstrap 4.
