The CSS object-fit property is used to specify how an
<img> or <video> should be resized to fit its container.
The CSS object-fit Property
The CSS object-fit property is used to specify how an <img> or <video> should
be resized to fit its container.
This property tells the content to fill the container in a variety of ways; such as
"preserve that aspect ratio" or "stretch up and take up as much space as
possible".
Look at the following image from Paris. This image is 400 pixels wide and 300 pixels high:
However, if we style the image above to be half its width (200 pixels) and
same height (300 pixels), it will look like this:
Example
img { width: 200px; height:
300px;}

We see that the image is being squished to fit the container of 200x300 pixels
(its original aspect ratio is destroyed).
Here is where the object-fit property comes
in. The object-fit property can take one of the
following values:
fill - This is default. The image is resized to fill the
given dimension. If necessary, the image will be stretched or squished to fit
contain - The image
keeps its aspect ratio, but is resized to fit within the given dimension
cover - The image keeps its aspect ratio
and fills the given dimension. The image will be clipped to fit
none - The image is not resized
scale-down - the image is
scaled down to the smallest version of none or
contain
Using object-fit: cover;
If we use object-fit: cover; the image keeps its aspect ratio
and fills the given dimension. The image will be clipped to fit:
Example
img { width: 200px; height:
300px; object-fit: cover;}

Using object-fit: contain;
If we use object-fit: contain; the image
keeps its aspect ratio, but is resized to fit within the given dimension:
Example
img { width: 200px; height:
300px; object-fit: contain;}

Using object-fit: fill;
If we use object-fit: fill; the image is
resized to fill the given dimension. If necessary, the image will be
stretched or squished to fit:
Example
img { width: 200px; height:
300px; object-fit: fill;}
Try it Yourself »
Using object-fit: none;
If we use object-fit: none; the image is not
resized:
Example
img { width: 200px; height:
300px; object-fit: none;}
Try it Yourself »
Using object-fit: scale-down;
If we use object-fit: scale-down; the image is
scaled down to the smallest version of none or
contain:
Example
img { width: 200px; height:
300px; object-fit: scale-down;}

Another Example
Here we have two images and we want them to fill the width of 50% of the browser window and 100% of the height.
In the following example we do NOT use object-fit, so when we resize the browser window, the aspect ratio of the images will be destroyed:
Example

In the next example, we use object-fit: cover;, so when we resize the browser window, the aspect ratio of the images
is preserved:
