Does Bootstrap 3 used Flexbox ?
Last Updated :

Bootstrap 3 used floats to handle the layout in place of the flexbox, however, Bootstrap 4 uses flexbox to handle the layout. The flexbox layout makes it easier to design a flexible responsive layout structure without using float or positioning. Therefore, we use Bootstrap 4 in place of Bootstrap 3 for the flexible design purpose.
Approach:
- We create a simple card for the online DSA Course and Blockchain Course of GFG. The bootstrap class d-flex defines a flexbox container.
- The direct HTML elements in the flexbox container are called flex items.
- The flex-direction specifies the direction of the flex items in the flexbox container.
- We use the flex-row class to move the flex items horizontally in the flexbox container.
- The justify-content class specifies the alignment of flex items along the flex-direction in a flexbox container.
- We use justify-content-end to align the flex items at the end of the flexbox container either horizontally or vertically based on the flex-direction.
- We use align-items-center to align the flex items at the center of the flexbox container either horizontally or vertically based on the flex-direction. This will apply to the opposite axis of the justify-content property.
Bootstrap CDN: We need to add the following CDN files within the HTML head element.
<link rel=”stylesheet” href=”https://cdn.jsdelivr.net/npm/bootstrap@4.6.1/dist/css/bootstrap.min.css”>
<script src=”https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.slim.min.js”></script>
<script src=”https://cdn.jsdelivr.net/npm/bootstrap@4.6.1/dist/js/bootstrap.bundle.min.js”></script>
Example: In this example, we have used flexbox to align the cards in the center vertically and to the right horizontally using the flex properties.
