| docs | Object fit | Use the object fit utilities to modify how the content of a [replaced element](https://developer.mozilla.org/en-US/docs/Web/CSS/Replaced_element), such as an `<img>` or `<video>`, should be resized to fit its container. | utilities | true |
How it works
Change the value of the object-fit property with our responsive object-fit utility classes. This property tells the content to fill the parent container in a variety of ways, such as preserving the aspect ratio or stretching to take up as much space as possible.
Classes for the value of object-fit are named using the format .object-fit-{value}. Choose from the following values:
containcoverfillscale(for scale-down)none
Examples
Add the object-fit-{value} class to the replaced element:
{{< example class="d-flex overflow-auto" >}} {{< placeholder width="140" height="120" class="object-fit-contain border rounded" text="Object fit contain" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="120" class="object-fit-cover border rounded" text="Object fit cover" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="120" class="object-fit-fill border rounded" text="Object fit fill" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="120" class="object-fit-scale border rounded" text="Object fit scale down" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="120" class="object-fit-none border rounded" text="Object fit none" markup="img" color="#868e96" background="#dee2e6" >}} {{< /example >}}
Responsive
Responsive variations also exist for each object-fit value using the format .object-fit-{breakpoint}-{value}, for the following breakpoint abbreviations: sm, md, lg, xl, and xxl. Classes can be combined for various effects as you need.
{{< example class="d-flex overflow-auto" >}} {{< placeholder width="140" height="80" class="object-fit-sm-contain border rounded" text="Contain on sm" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="80" class="object-fit-md-contain border rounded" text="Contain on md" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="80" class="object-fit-lg-contain border rounded" text="Contain on lg" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="80" class="object-fit-xl-contain border rounded" text="Contain on xl" markup="img" color="#868e96" background="#dee2e6" >}} {{< placeholder width="140" height="80" class="object-fit-xxl-contain border rounded" text="Contain on xxl" markup="img" color="#868e96" background="#dee2e6" >}} {{< /example >}}
Video
The .object-fit-{value} and responsive .object-fit-{breakpoint}-{value} utilities also work on <video> elements.
<video src="..." class="object-fit-contain" autoplay></video>
<video src="..." class="object-fit-cover" autoplay></video>
<video src="..." class="object-fit-fill" autoplay></video>
<video src="..." class="object-fit-scale" autoplay></video>
<video src="..." class="object-fit-none" autoplay></video>
