How can I create a fullscreen responsive background image with CSS?

Creating Fullscreen Responsive Background Image Using CSS

In web design, creating a fullscreen responsive background image can enhance the visual appeal of your webpages. However, encountering issues where the image doesn't fully cover the page can be frustrating. Consider the following example:

body {
    background: url('http://www.androidtapp.com/wp-content/uploads/2012/11/Angry-Birds-Star-Wars-Menu.png');
}

In this code, the background image is repeated on the rightmost end due to insufficient coverage. To rectify this, let's explore a solution using CSS.

Using the Background-Size Property

The background-size property allows you to specify the dimensions of the background image. By setting it to cover, the image will stretch to fill the entire page, ensuring full coverage.

body {
    background: url('http://www.androidtapp.com/wp-content/uploads/2012/11/Angry-Birds-Star-Wars-Menu.png') cover;
}

Example with Additional Styles

In modern browsers, you can use the following CSS to create a fullscreen responsive background image with fixed positioning:

background: url(image.jpg) fixed 50% / cover;

This shorthand notation combines the background-image, background-attachment, background-position, and background-size properties to achieve the desired effect.

Shorthand Syntax for Responsive Background Image

For browsers that support CSS3, you can use the following shorthand syntax:

background: url(image.jpg) fixed center / cover;

This syntax sets the image as the background, fixes it in place, positions it in the center, and ensures it covers the entire page.

Note for Safari Browser

It's worth noting that Safari has a known issue with the / shorthand for specifying background-size. To avoid this bug, use the following syntax instead:

background: url(image.jpg) fixed 50%;
background-size: cover;

By incorporating these CSS techniques, you can create stunning fullscreen responsive background images that enhance the user experience and make your webpages stand out.
