![]() Imagine looking out the window from a moving car. Oftentimes scrolling effects are called parallax meaning some elements are made to look like they are deep in the background, making them appear to move slower than other elements that are closer to the foreground while scrolling is taking place. In other words, it detects when elements are in the viewport and then alters CSS transform property values on those elements to create scrolling effects. Locomotive scroll is a simple scroll library, built as a layer on top of ayamflow’s virtual-scroll, it provides smooth scrolling with support for parallax effects, toggling classes, and triggering event listeners when elements are in the viewport. Let’s look at the basics of using Locomotive-Scroll JavaScript and how to leverage it to for delightful user experiences. The homepage will give you a good sense of how it works and feels. You could probably consider this “scrolljacking” so if you hate that generally, you might hate this, but UX research seems rather mixed on whether it’s actually bad or not. You might also call it a “smooth scrolling” library, but it doesn’t leverage native smooth scrolling - it does just the opposite by virtualizing scrolling and ensuring it’s always smooth. It lets you perform a variety of scrolling effects, like parallax and triggering/controlling animations at scroll points. 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.I was recently looking for a way to perform scrolling effects on a project and I stumbled on the Locomotive S croll library. 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. ![]() The parallax effect is one of the niftiest little tricks that you can use on your landing page to attract the attention of your visitors.
