CSS allows you to resize images to fit a specific container, without stretching the image. Here are a few ways to accomplish this:
- Using the "object-fit" property: This property allows you to specify how an image should be resized to fit its container. The "contain" value will make the image fit within the container while maintaining its aspect ratio, and the "cover" value will make the image fill the container while maintaining its aspect ratio.
img {
width: 100%;
height: 100%;
object-fit: contain; /* or cover */
}
- Using the "background-size" property: This property allows you to specify the size of a background image. The "contain" value will make the image fit within the container while maintaining its aspect ratio, and the "cover" value will make the image fill the container while maintaining its aspect ratio.
div {
width: 100%;
height: 100%;
background-image: url(image.jpg);
background-size: contain; /* or cover */
background-repeat: no-repeat;
}
- Using the "max-width" and "max-height" properties: This method allows you to set the maximum width and height of an image, while maintaining its aspect ratio.
img {
max-width: 100%;
max-height: 100%;
}
- Using the "width" and "height" properties with a percentage value: This method allows you to set the width and height of an image as a percentage of its container, while maintaining its aspect ratio.
img {
width: 100%;
height: auto;
}
In all these examples, the image will be resized to fit the container without stretching. Note that these techniques may not work on older browsers, so you may need to use a polyfill or a JavaScript fallback.
- Using the "background-position" property: This property allows you to specify the position of a background image within its container. By default, the image is positioned at the top-left corner of the container. However, you can use keywords like "center", "top", "bottom", "left", "right" or use pixel values to adjust the position of the image.
div {
width: 100%;
height: 100%;
background-image: url(image.jpg);
background-size: contain;
background-repeat: no-repeat;
background-position: center; /* or use pixel values */
}
- Using the "background-repeat" property: This property allows you to specify how a background image should be repeated. By default, the image is repeated both horizontally and vertically. However, you can use the "no-repeat" value to prevent repeating of an image, "repeat-x" to repeat horizontally and "repeat-y" to repeat vertically.
div {
width: 100%;
height: 100%;
background-image: url(image.jpg);
background-size: contain;
background-repeat: no-repeat; /* or repeat-x or repeat-y*/
}
- Using the "background-clip" property: This property allows you to specify the area of an element where the background image should be painted. By default, the background image is painted within the padding box of the element. However, you can use the "border-box" value to paint the background image within the border box of the element, or the "content-box" value to paint the background image within the content box of the element.
div {
width: 100%;
height: 100%;
background-image: url(image.jpg);
background-size: contain;
background-repeat: no-repeat;
background-clip: border-box; /* or content-box*/
}
- Using the "background-origin" property: This property allows you to specify the area of an element where the background image should be positioned. By default, the background image is positioned within the padding box of the element. However, you can use the "border-box" value to position the background image within the border box of the element, or the "content-box" value to position the background image within the content box of the element.
div {
width: 100%;
height: 100%;
background-image: url(image.jpg);
background-size: contain;
background-repeat: no-repeat;
background-origin: border-box; /* or content-box*/
}
It is worth noting that there is also a shorthand property for all background properties:
div {
width: 100%;
height: 100%;
background: url(image.jpg) no-repeat center/contain border-box;
}
It is also important to consider browser compatibility when using these CSS properties. Some of the properties might not work on older browsers, so it is recommended to use feature detection and polyfills to ensure the compatibility.

Q: What is the difference between using "contain" and "cover" for the "background-size" property?
A: "Contain" will scale the image to fit the div while maintaining its aspect ratio, meaning that the entire image will be visible within the div. "Cover" will also scale the image to fit the div but will fill the entire div, meaning that some parts of the image might be hidden. -
Q: How can I prevent the background image from repeating within the div?
A: You can use the "background-repeat" property with the value of "no-repeat" to prevent the background image from repeating.
div {

height: 100%;
background-image: url(image.jpg);
background-size: contain;
background-repeat: no-repeat;
}
- Q: How can I center the background image within the div?

background-image: url(image.jpg);
background-size: contain;
background-repeat: no-repeat;
background-position: center;
}
- Q: Is it possible to use a shorthand property for all background properties?
