By using this site, you agree to the Terms of Use and Privacy Policy. Websites often use this for informational pages, where you have some text in the foreground and an image in the background that scrolls more slowly to create a more interesting experience for the user. This page has some examples of web pages with parallax scrolling. With React, it is quick and simple to create the parallax scrolling effect with the react-parallax library. In this article, we will make an app that displays a list of images in the background with tags text in the foreground.

These sites show the world how parallax scrolling should be done.

The images will be provided by the Pixabay API. You can register for an API key at Pixabay. To start building the app, we create the app by running Create React App. Run npx create-react-app scrolling-app to build the skeleton of the app. Once that finishes running, we install some packages. We need to install axios to get images from the Pixabay API, Bootstrap for styling, React Router for routing URLs into the page we create, and react-parallax to create the parallax scrolling effect. Next, we write the code for our parallax scrolling app. In App. We added a top bar which we will create and a route to the home page with React Router.

Next, we create the main page of our parallax scrolling app.

Create a file called HomePage. In this page, we load the images with the Pixabay API in the loadImages function when the pages first loads. We check if the page is initialized. If not, we load the images.

Applying the effect

Once the images are loaded, we display them by mapping the image data into the Parallax components provided by react-parallax. The strength prop specifies the number of pixels that are translated to create parallax scrolling. The higher the number, the more obvious the difference in scroll speed between the foreground and background will be.

Inside the Parallax component, we specify the content we want to display. We specified that we display the tag text that comes with the image from the Pixabay API.

The renderLayer prop lets us display elements between the foreground and background. We can animate the element defined here by using the percentage parameter in the function adjust dimensions. For example, on this page, we adjust the width and height with the percentage.
