Css img width container

object-fit

The object-fit CSS property sets how the content of a replaced element, such as an or , should be resized to fit its container.

You can alter the alignment of the replaced element’s content object within the element’s box using the object-position property.

Try it

Syntax

object-fit: contain; object-fit: cover; object-fit: fill; object-fit: none; object-fit: scale-down; /* Global values */ object-fit: inherit; object-fit: initial; object-fit: revert; object-fit: revert-layer; object-fit: unset; 

The object-fit property is specified as a single keyword chosen from the list of values below.

Values

The replaced content is scaled to maintain its aspect ratio while fitting within the element’s content box. The entire object is made to fill the box, while preserving its aspect ratio, so the object will be «letterboxed» if its aspect ratio does not match the aspect ratio of the box.

The replaced content is sized to maintain its aspect ratio while filling the element’s entire content box. If the object’s aspect ratio does not match the aspect ratio of its box, then the object will be clipped to fit.

The replaced content is sized to fill the element’s content box. The entire object will completely fill the box. If the object’s aspect ratio does not match the aspect ratio of its box, then the object will be stretched to fit.

The replaced content is not resized.

The content is sized as if none or contain were specified, whichever would result in a smaller concrete object size.

Formal definition

Formal syntax

object-fit =

How to Auto-Resize the Image to fit an HTML Container

It is not complicated to make the image stretch to fit the container. CSS makes it possible to resize the image so as to fit an HTML container. To auto-resize an image or a video, you can use various CSS properties, which are described in this tutorial. It’s very easy if you follow the steps described below.

Let’s see an example and try to discuss each part of the code.

Create HTML

body> div class="box"> img src="https://pp.userapi.com/c622225/v622225117/10f33/47AAEI48pJU.jpg?ava=1" alt="Example image"/> div> body>

Add CSS

  • Set the height and width of the .
  • You can add border to your by using the border property with values of border-width, border-style and border-color properties.
  • Set the height and width to «100%» for the image.
.box < width: 30%; height: 200px; border: 5px dashed #f7a239; > img < width: 100%; /* takes the 100 % width of its container (.box div)*/ height: 100%; /* takes the 100 % height of its container (.box div)*/ >

Let’s combine the code parts and see how it works! Here is the result of our code.

Example of auto-resizing an image with the width and height properties:

html> html> head> title>Title of the document title> style> body < background: crimson; > .box < width: 40%; height: 200px; border: 5px solid gold; > img < width: 100%; height: 100%; > style> head> body> div class="box"> img src="/uploads/media/default/0001/05/f32e5dec539f7c03f44990789d49d67c20c3e040.jpg" alt="Example image" /> div> body> html>

Here’s our result:

fixed width image

The image takes 40% width and 200px height of its container (red background).

In the example below, we use the «cover» value of the object-fit property. When using the «cover» value, the aspect ratio of the content is sized while filling the element’s content box. It will be clipped to fit the content box.

You can use other values like contain, scale-down, etc. for object-fit and make sure to check them as well. Still, we’ll mostly use the cover value as we like our image to cover its container as much as it doesn’t hurt the aspect ratio.

Example of resizing an image using the object-fit property set to “cover”:

html> html> head> style> .container < width: 60%; height: 300px; border: 5px solid gold; > img < width: 100%; height: 100%; object-fit: cover; > style> head> body> div class="container"> img src="https://images.unsplash.com/photo-1581974267369-3f2fe3b4545c?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=500&q=60" alt="Image" /> div> body> html>

This image will help you understand it better! See how the image fits its aspect ratio based on the screen size changes!

See another example where the image size is set manually, and the object-fit property is set as well. In this case, when the browser is resized, the image will preserve its aspect ratio and won’t be resized according to the container.

Example of resizing an image using the object-fit property:

html> html> head> style> body < text-align: center; > img < width: 400px; height: 200px; object-fit: cover; > style> head> body> img src="https://images.unsplash.com/photo-1581974267369-3f2fe3b4545c?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=500&q=60" alt="Image" /> body> html>

Let’s see this example without object-fit property first! Ugly, huh? You’re right!

without object fit property

with object fit property

In the next example, we use the max-width and the rules can be applied to max-height as well. The max-height property sets the maximum height of an element, and the max-width property sets the maximum width of an element. To resize an image proportionally, set either the height or width to «100%», but not both. If you set both to «100%», the image will be stretched.

Example of auto-resizing an image with the max-width and max-height properties:

html> html> head> title>Title of the document title> style> img < width: 600px; /* image initial width */ > div < border: 2px dotted #000000; > .container < width: 500px; /* container initial width */ border: 2px solid gold; > style> head> body> div class="container"> img src="/uploads/media/default/0001/05/8dc771228e65a66d63299043ad824e26fb9b879f.jpg" alt="Circle portrait" /> div> body> html>

Here’s the problem! Our image is out of its container because its width (600px) is bigger than its container width (500px)!

image out of the container

To solve our problem, we’ll use the max-width: 100% property, which not allows the image to take any width bigger than its container (here, not more than 500px).

image inside the container

Now, it will scale down when the width is less than 500px. The same rule is applicable for max-height property.

html> html> head> title>Title of the document title> style> img < width: 600px; max-width: 100%; /* add this line */ > .container < height: 100%; width: 500px; border: 2px solid gold; > style> head> body> div class="container"> img src="https://www.w3docs.com//uploads/media/default/0001/05/8dc771228e65a66d63299043ad824e26fb9b879f.jpg" alt="image example" /> div> body> html>

To use an image as a CSS background, use the background-size property. This property offers two special values: contain and cover. Let’s see examples of these values.

Example of resizing an image using the background-size property set to “contain” & «cover»:

html> html> head> title>Title of the document title> style> .box < width: 300px; height: 250px; border: 5px solid gold; background-image: url("https://images.unsplash.com/photo-1582093236149-516a8be696fe?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=500&q=60"); background-size: contain; /* try other properties here like cover, contain, etc */ background-repeat: no-repeat; background-position: 50% 50%; > style> head> body> div class="box"> div> body> html>

Here’s what contain will give us!

bg contain

bg cover

Much better! I hope you’ve enjoyed it all!

CSS The object-fit Property

The CSS object-fit property is used to specify how an or should be resized to fit its container.

The CSS object-fit Property

The CSS object-fit property is used to specify how an or 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:

Paris

However, if we style the image above to be half its width (200 pixels) and same height (300 pixels), it will look like this:

Paris

Example

We see that the image is being squished to fit the container of 200×300 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:

Paris

Example

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:

Paris

Example

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:

Paris

Example

Using object-fit: none;

If we use object-fit: none; the image is not resized:

Paris

Example

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 :

Paris

Example

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

Norway Paris

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

Example

Norway Paris
