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
.img-fluid.
max-width: 100%; and
height: auto; are applied to the image so that it scales with the parent element.
<img src="..." class="img-fluid" alt="Responsive image">
SVG images and IE 10
In Internet Explorer 10, SVG images with .img-fluid are disproportionately sized. To fix this, add width: 100% \9; where necessary. This fix improperly sizes other image formats, so Bootstrap doesn’t apply it automatically.
Image thumbnails
In addition to our
border-radius utilities, you can use
.img-thumbnail to give an image a rounded 1px border appearance.
<img src="..." alt="..." class="img-thumbnail">
Aligning images
Align images with the
helper float classes or
text alignment classes.
block-level images can be centered using
the
.mx-auto margin utility class.
<img src="..." class="rounded float-left" alt="...">
<img src="..." class="rounded float-right" alt="...">
<img src="..." class="rounded mx-auto d-block" alt="...">
<div class="text-center">
<img src="..." class="rounded" alt="...">
</div>
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.
<picture>
<source srcset="..." type="image/svg+xml">
<img src="..." class="img-fluid img-thumbnail" alt="...">
</picture>
