# 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.

## 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):

```html
<svg class="docs-placeholder-img object-fit-contain border rounded" width="140" height="120" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Object fit contain" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Object fit contain</text></svg>

<svg class="docs-placeholder-img object-fit-cover border rounded" width="140" height="120" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Object fit cover" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Object fit cover</text></svg>

<svg class="docs-placeholder-img object-fit-fill border rounded" width="140" height="120" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Object fit fill" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Object fit fill</text></svg>

<svg class="docs-placeholder-img object-fit-scale border rounded" width="140" height="120" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Object fit scale down" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Object fit scale down</text></svg>

<svg class="docs-placeholder-img object-fit-none border rounded" width="140" height="120" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Object fit none" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Object fit none</text></svg>

```

## 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.

```html
<svg class="docs-placeholder-img object-fit-sm-contain border rounded" width="140" height="80" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Contain on sm" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Contain on sm</text></svg>

<svg class="docs-placeholder-img object-fit-md-contain border rounded" width="140" height="80" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Contain on md" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Contain on md</text></svg>

<svg class="docs-placeholder-img object-fit-lg-contain border rounded" width="140" height="80" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Contain on lg" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Contain on lg</text></svg>

<svg class="docs-placeholder-img object-fit-xl-contain border rounded" width="140" height="80" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Contain on xl" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Contain on xl</text></svg>

<svg class="docs-placeholder-img object-fit-xxl-contain border rounded" width="140" height="80" xmlns="http://www.w3.org/2000/svg" role="img" aria-label="Placeholder: Contain on xxl" preserveAspectRatio="xMidYMid slice" focusable="false"><title>Placeholder</title><rect width="100%" height="100%" fill="#dee2e6"/><text x="50%" y="50%" fill="#868e96" dy=".3em">Contain on xxl</text></svg>

```

## Video

The `.object-fit-{value}` and responsive `.object-fit-{breakpoint}-{value}` utilities also work on `<video>` elements.

```html
<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>
```

## CSS

### Sass utilities API

Object fit utilities are declared in our utilities API in `scss/_utilities.scss`. [Learn how to use the utilities API.](/utilities/api/#using-the-api)

```scss
&#34;object-fit&#34;: (
  responsive: true,
  property: object-fit,
  values: (
    contain: contain,
    cover: cover,
    fill: fill,
    scale: scale-down,
    none: none,
