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.

{% capture callout %}

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. {% endcapture %} {% include callout.html content=callout type=“warning” %}

Image thumbnails

In addition to our [border-radius utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/), you can use .img-thumbnail to give an image a rounded 1px border appearance.

Aligning images

Align images with the [helper float classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/float) or [text alignment classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/#text-alignment). block-level images can be centered using [the .mx-auto margin utility class]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/#horizontal-centering).

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.
