This code creates a CSS-only horizontal scrolling parallax gallery. It arranges images in a scrollable horizontal layout. Each image responds with a parallax effect based on scroll speed, creating a dynamic visual experience. It helps showcase a series of photos in an engaging, horizontally-scrollable manner without JavaScript.

You can use this code on websites to showcase photo galleries or visual portfolios. It’s great for displaying multiple images in a horizontal scroll, giving visitors an interactive and engaging way to explore your photos.

How to Create Horizontal Scrolling Parallax Gallery In Css

1. First of all, copy the following HTML code into your project. This creates the structure for your image gallery. Replace the image URLs in the HTML code (<img src="...">) with your desired image URLs. Ensure each <img> tag is within the <div class="img-wrapper"> to maintain the gallery layout.

2. Now, copy the CSS code into your stylesheet or HTML file. This code provides the styling and functionality for the gallery. Modify the CSS classes (.slower, .faster, .last, etc.) to adjust the speed and scale of the parallax effect for each image. Experiment with these values to achieve the desired visual effect.
