How TO - Parallax Scrolling


Learn how to create a "parallax" scrolling effect with CSS.


Parallax

Parallax scrolling is a web site trend where the background content (i.e. an image) is moved at a different speed than the foreground content while scrolling. Click on the links below to see the difference between a website with and without parallax scrolling.

Demo with parallax scrolling

Demo without parallax scrolling

Note: Parallax scrolling does not always work on mobile devices/smart phones. However, you can use media queries to turn off the effect on mobile devices (see last example on this page).


How To Create a Parallax Scrolling Effect

Use a container element and add a background image to the container with a specific height. Then use the background-attachment: fixed to create the actual parallax effect. The other background properties are used to center and scale the image perfectly:

Example with pixels

<style>
.parallax {
    /* The image used */
    background-image: url("img_parallax.jpg");

    /* Set a specific height */
    height: 500px;

    /* Create the parallax scrolling effect */
    background-attachment: fixed;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
}
</style>

<!-- Container element -->
<div class="parallax"></div>

The example above used pixels to set the height of the image. If you want to use percent, for example 100%, to make the image fit the whole screen, set the height of the parallax container to 100%. Note: You must also apply height: 100% to both <html> and <body>:

Example with percent

body, html {
    height: 100%;
}

.parallax {
    /* The image used */
    background-image: url("img_parallax.jpg");

    /* Full height */
    height: 100%;

    /* Create the parallax scrolling effect */
    background-attachment: fixed;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
}

Some mobile devices have a problem with background-attachment: fixed. However, you can use media queries to turn off the parallax effect for mobile devices:

Example

/* Turn off parallax scrolling for all tablets and phones. Increase/decrease the pixels if needed */
@media only screen and (max-device-width: 1366px) {
    .parallax {
        background-attachment: scroll;
    }
}
