Images

Documentation and examples for opting images into responsive behavior (so they never become larger than their parent elements) and add lightweight styles to them—all via classes.

Responsive images

Images in Bootstrap are made responsive with .c-img-fluid. max-width: 100%; and height: auto; are applied to the image so that it scales with the parent element.

Image thumbnails

In addition to our border-radius utilities, you can use .c-img-thumbnail to give an image a rounded 1px border appearance.

Aligning images

Align images with the helper float classes or text alignment classes. block-level images can be centered using the .c-mx-auto margin utility class.

Picture

If you are using the <picture> element to specify multiple <source> elements for a specific <img>, make sure to add the .img-* classes to the <img> and not to the <picture> tag.
