Html image width div

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.

Responsive Web Design — Images

Resize the browser window to see how the image scales to fit the page.

Using The width Property

If the width property is set to a percentage and the height property is set to «auto», the image will be responsive and scale up and down:

Example

Notice that in the example above, the image can be scaled up to be larger than its original size. A better solution, in many cases, will be to use the max-width property instead.

Using The max-width Property

If the max-width property is set to 100%, the image will scale down if it has to, but never scale up to be larger than its original size:

Example

Add an Image to The Example Web Page

Example

Background Images

Background images can also respond to resizing and scaling.

Here we will show three different methods:

1. If the background-size property is set to «contain», the background image will scale, and try to fit the content area. However, the image will keep its aspect ratio (the proportional relationship between the image’s width and height):

Example

div <
width: 100%;
height: 400px;
background-image: url(‘img_flowers.jpg’);
background-repeat: no-repeat;
background-size: contain;
border: 1px solid red;
>

2. If the background-size property is set to «100% 100%», the background image will stretch to cover the entire content area:

Example

div <
width: 100%;
height: 400px;
background-image: url(‘img_flowers.jpg’);
background-size: 100% 100%;
border: 1px solid red;
>

3. If the background-size property is set to «cover», the background image will scale to cover the entire content area. Notice that the «cover» value keeps the aspect ratio, and some part of the background image may be clipped:

Example

div <
width: 100%;
height: 400px;
background-image: url(‘img_flowers.jpg’);
background-size: cover;
border: 1px solid red;
>

Different Images for Different Devices

A large image can be perfect on a big computer screen, but useless on a small device. Why load a large image when you have to scale it down anyway? To reduce the load, or for any other reasons, you can use media queries to display different images on different devices.

Here is one large image and one smaller image that will be displayed on different devices:

Example

/* For width smaller than 400px: */
body background-image: url(‘img_smallflower.jpg’);
>

/* For width 400px and larger: */
@media only screen and (min-width: 400px) body <
background-image: url(‘img_flowers.jpg’);
>
>

You can use the media query min-device-width , instead of min-width , which checks the device width, instead of the browser width. Then the image will not change when you resize the browser window:

Example

/* For devices smaller than 400px: */
body background-image: url(‘img_smallflower.jpg’);
>

/* For devices 400px and larger: */
@media only screen and (min-device-width: 400px) body <
background-image: url(‘img_flowers.jpg’);
>
>

The HTML Element

The HTML element gives web developers more flexibility in specifying image resources.

The most common use of the element will be for images used in responsive designs. Instead of having one image that is scaled up or down based on the viewport width, multiple images can be designed to more nicely fill the browser viewport.

The element works similar to the and elements. You set up different sources, and the first source that fits the preferences is the one being used:

Example

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;
