Parallax scrolling is a computer graphics technique in which background images move past the camera more slowly than the foreground images, creating an illusion of depth in a 2D scene. Use parallax scrolling in the right places.Pros and cons of fixing the background position.Handling mobile browser compatibility issues.How to implement the parallax effect in CSS.Looks like magic, right? Let’s go backstage and see how the magic happens! As the user scrolls down, the parallax effect makes the scene fall away to reveal the content below: The hero section contains a rural scene of a hiker peering across a valley to a hill station. We’ll review several CSS parallax examples, use cases, and best practices.Ī famous and well-executed example of parallax scrolling is the Firewatch computer game website. In this article, we’ll discuss why you should consider using parallax scrolling, demonstrate how to implement it with CSS, and explore the benefits of using CSS instead of JavaScript. However, there is some nuance to this that we’ll clarify later. In the simplest of terms, parallax scrolling is a three-dimensional effect for adding more depth to a webpage. Parallax scrolling can improve a website’s browsing experience by making it more dynamic and immersive. The markup doesn’t look all that appealing right now, so before implementing the parallax effect, paste the following code in your previously created styles.Editor’s note: This article was last updated on 17 March 2023 to include additional information about best practices for implementing a parallax scroll. Now, create a styles.css file and then link it to the HTML file by putting the following code in the tag: Code language: HTML, XML ( xml ) Implementing parallax using CSS It is easier to notice the difference when there are 2 static/non-parallax sections to compare against. This will create 3 sections of which only the 2nd will have the parallax effect. Have a nice day! Code language: HTML, XML ( xml ) The sound that occurs when you snap your fingers is made by your Create a file named index.html and copy/paste the following code: Pure CSS Parallax Effect Fun fact: Putting together some markupįirst off, we need some HTML. We will be making use of translateZ() and scale() transformations. This means we will be making use of mainly two CSS properties: perspective and transform. To counter this decrease in size we can scale it back to its original size. Because perceivable distance is increased, the layer may appear smaller. To achieve both these conditions, we have to increase the perceivable distance between the user and the layer, then shift it along the negative Z-axis. Alter the way the parallax layer is perceived in such a way that it looks like it’s moving relatively faster or slower, without deviating from its original size.So putting it simply, the conditions that have to be satisfied for a parallax effect to be created are: You might have observed the parallax effect while you’re in the car where objects further away seem to move slower than other cars in the road. You might have seen applications of the parallax effect as early as 2D games where the background appears to shift slower in comparison to the foreground. The parallax effect is to make two (for the sake of explaining) layers on top of each other moving at a constant speed appear like the layer on top is moving relatively faster than the one beneath it. However, if you want to skip and get to writing some code instead, head on over to the next topic. Understanding the conditions required to create a parallax effect helps to implement it correctly. This article will demonstrate how you can use modern CSS to create a easy to maintain beautiful parallax effect. Hacky tricks like background-position are quite difficult to maintain however. CSS has matured a lot over the past few years, and this means that there’s a lot of flexibility as to how something should be done.
