docs 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. content true

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.

{% include icons/placeholder.svg width="100%" height="250" class="bd-placeholder-img-lg img-fluid" text="Responsive image" %}

{% highlight html %} Responsive image {% endhighlight %}

{% capture callout %}

SVG images and Internet Explorer

In Internet Explorer 10 and 11, SVG images with .img-fluid are disproportionately sized. To fix this, add width: 100%; or .w-100 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.

{% include icons/placeholder.svg width="200" height="200" class="img-thumbnail" title="A generic square placeholder image with a white border around it, making it resemble a photograph taken with an old instant camera" %}

{% highlight html %} ... {% endhighlight %}

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).

{% include icons/placeholder.svg width="200" height="200" class="rounded float-left" %} {% include icons/placeholder.svg width="200" height="200" class="rounded float-right" %}

{% highlight html %} ... ... {% endhighlight %}

{% include icons/placeholder.svg width="200" height="200" class="rounded mx-auto d-block" %}

{% highlight html %} ... {% endhighlight %}

{% include icons/placeholder.svg width="200" height="200" class="rounded" %}

{% highlight html %}

...
{% endhighlight %}

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.
