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.
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.
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.
In addition to our [border-radius utilities]({{ site.baseurl }}/utilities/borders/), you can use `.img-thumbnail` to give an image a rounded 1px border appearance.
<imgdata-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">
Align images with the [helper float classes]({{ site.baseurl }}/utilities/responsive-helpers/#responsive-floats) or [text alignment classes]({{ site.baseurl }}/utilities/typography/#text-alignment). `block`-level images can be centered using [the `.mx-auto` margin utility class]({{ site.baseurl }}/utilities/spacing/#horizontal-centering).
