## 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">
|
||
<img data-src="holder.js/100px250" class="img-fluid" alt="Generic responsive image">
|
||
</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.
|
||
{% endcallout %}
|
||
|
||
## 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.
|
||
|
||
<div class="bd-example bd-example-images">
|
||
<img data-src="holder.js/200x200" class="img-thumbnail" alt="A generic square placeholder image with a white border around it, making it resemble a photograph taken with an old instant camera">
|
||
</div>
|
||
|
||
{% highlight html %}
|
||
<img src="..." alt="..." class="img-thumbnail">
|
||
{% 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).
|
||
|
||
<div class="bd-example bd-example-images">
|
||
<img data-src="holder.js/200x200" class="rounded float-left" alt="A generic square placeholder image with rounded corners">
|
||
<img data-src="holder.js/200x200" class="rounded float-right" alt="A generic square placeholder image with rounded corners">
|
||
</div>
|
||
|
||
{% highlight html %}
|
||
<img src="..." class="rounded float-left" alt="...">
|
||
<img src="..." class="rounded float-right" alt="...">
|
||
{% endhighlight %}
|
||
|
||
<div class="bd-example bd-example-images">
|
||
<img data-src="holder.js/200x200" class="rounded mx-auto d-block" alt="A generic square placeholder image with rounded corners">
|
||
</div>
|
||
|
||
{% highlight html %}
|
||
<img src="..." class="rounded mx-auto d-block" alt="...">
|
||
{% endhighlight %}
|
||
|
||
<div class="bd-example bd-example-images">
|
||
<div class="text-center">
|
||
<img data-src="holder.js/200x200" class="rounded" alt="A generic square placeholder image with rounded corners">
|
||
</div>
|
||
</div>
|
||
|
||
{% highlight html %}
|
||
<div class="text-center">
|
||
<img src="..." class="rounded" alt="...">
|
||
</div>
|
||
{% 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.
|
||
|
||
{% highlight html %}
|
||
<picture>
|
||
<source srcset="..." type="image/svg+xml">
|
||
<img src="..." class="img-fluid img-thumbnail" alt="...">
|
||
</picture>
|
||
{% endhighlight %}
