Due to the much smaller screen sizes of smartphones and tablets, the images used on a desktop PC for parallax scroll designs are often too large for these devices, both in terms of dimensions and file size. While the parallax scrolling effect can greatly enhance the visual appearance of a website’s desktop version, it is less suitable for mobile devices. Parallax scrolling is not suitable for mobile websites Alternatively, you can specify the height of the background image in percent. The other background properties are used to center and scale the image. The attribute "background-attachment: fixed" creates the parallax scroll effect by fixing the background image. * Create the parallax scrolling effect */īackground-size: cover /* scales the image to cover the entire container */ The properties of the class are defined in CSS: A class is assigned to the container and a background image with a specific height is added. To implement the parallax scroll effect into a website with HTML5 and CSS, a container element is used to design the website.

From the 1980s onwards, the technique was used in 2D computer graphics and video games, especially by Arcade. Walt Disney applied parallaxing in his film classics such as Snow White, Bambi and Fantasia to create an illusion of movement and depth. As a result, the faster moving layers are perceived as closer to the camera. This technique uses multiple layers that are each moved by a different amount in the same direction. Initially known as "parallaxing", it originated from the multiplane camera technique which was introduced to animation in the 1930s. With this technique, the background of a web page moves at a slower speed than the foreground while scrolling, creating the illusion of three-dimensionality on a two-dimensional website. Parallax scrolling is a special scrolling technique that is used in web design to create an impression of depth. Figure: Parallax Scrolling - Author: Seobility - License: CC BY-SA 4.0
