Object fit

Use the object fit utilities to modify how the content of a 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 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:

Placeholder : Object fit contain Placeholder : Object fit cover Placeholder : Object fit fill Placeholder : Object fit scale down Placeholder : Object fit none
html 
<img src="..." class="object-fit-contain border" alt="..."> 
<img src="..." class="object-fit-cover border" alt="..."> 
<img src="..." class="object-fit-fill border" alt="..."> 
<img src="..." class="object-fit-scale border" alt="..."> 
<img src="..." class="object-fit-none border" alt="...">

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.

Placeholder : Contain on sm Placeholder : Contain on md Placeholder : Contain on lg Placeholder : Contain on xl Placeholder : Contain on xxl
html 
<img src="..." class="object-fit-sm-contain border" alt="..."> 
<img src="..." class="object-fit-md-contain border" alt="..."> 
<img src="..." class="object-fit-lg-contain border" alt="..."> 
<img src="..." class="object-fit-xl-contain border" alt="..."> 
<img src="..." class="object-fit-xxl-contain border" alt="...">

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>
