description: 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.

<div class="bd-example">
2015-08-27 23:26:00 +02:00
<img data-src="holder.js/100px250" class="img-fluid" alt="Generic responsive image">
2014-07-10 06:17:22 +02:00
</div>

{% highlight html %}
<img src="..." class="img-fluid" alt="Responsive image">

{% endhighlight %}
{% callout warning %}
#### 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]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/), you can use `.img-thumbnail` to give an image a rounded 1px border appearance.

## Aligning images
2017-08-11 16:40:41 +02:00
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).

## 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.
{% highlight html %}
<picture>
<source srcset="..." type="image/svg+xml">
<img src="..." class="img-fluid img-thumbnail" alt="...">
</picture>
{% endhighlight %}
