description: 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.

## How it works
Change the value of the [`object-fit` property](https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit) 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:
-`contain`
-`cover`
-`fill`
-`scale` (for scale-down)
-`none`
## Examples
Add the `object-fit-{value}` class to the [replaced element](https://developer.mozilla.org/en-US/docs/Web/CSS/Replaced_element):
{{<placeholderwidth="140"height="120"class="object-fit-contain border rounded"text="Object fit contain"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="120"class="object-fit-cover border rounded"text="Object fit cover"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="120"class="object-fit-fill border rounded"text="Object fit fill"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="120"class="object-fit-scale border rounded"text="Object fit scale down"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="120"class="object-fit-none border rounded"text="Object fit none"markup="img"color="#868e96"background="#dee2e6">}}
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.
{{<placeholderwidth="140"height="80"class="object-fit-sm-contain border rounded"text="Contain on sm"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="80"class="object-fit-md-contain border rounded"text="Contain on md"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="80"class="object-fit-lg-contain border rounded"text="Contain on lg"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="80"class="object-fit-xl-contain border rounded"text="Contain on xl"markup="img"color="#868e96"background="#dee2e6">}}
{{<placeholderwidth="140"height="80"class="object-fit-xxl-contain border rounded"text="Contain on xxl"markup="img"color="#868e96"background="#dee2e6">}}
