Bootstrap 5 Images

Create responsive images and image shapes with Bootstrap's image styles.

Bootstrap provides classes that can be used when working with the img element. Most of these are utility classes that can be applied to any element (not just images). However, there is a class specifically for responsive images.

Responsive Images

Bootstrap provides the .img-fluid class to make an image scale appropriately across devices. This class applies max-width: 100% and height: auto to the image. This ensures that the image scales to the parent element.

To see the following image scale, open the preview in a new window, then resize your browser.

Rounded Corners & Thumbnails

You can use Bootstrap to render images with rounded corners or as a circle. This is acheived with the .rounded-* utility classes.

You can also use the .img-thumbnail class to give it a rounded 1 pixel border.

The utility classes can be applied to any element (not just images). The border radius classes are:

Image Alignment

You can use either Bootstrap's helper float classes or text alignment classes to align images horizontally.


Use Bootstrap's .float-start, .float-end, and .float-*-* classes to float an image to the left or right. These classes float an element to the left or right, or disable floating, based on the current viewport size.

The responsive float classes are:

The .float-none and .float-*-none classes disable floating.

Centering Block-Level Images

Use Bootstrap's .mx-auto to center an image with .d-block applied. This sets margin: auto.

You can also use any of the responsive .mx-*-auto classes.

Centering Non-Block-Level Images

You can use Bootstrap's .text-center class on the image's parent to center a non-block-level image.

See the Bootstrap 5 documentation for more about text alignment.
