Let’s create a “Scroll Drive All The Things” effect using HTML, CSS, and JavaScript. This effect will give the impression of driving all the elements on the screen as the user scrolls, creating a dynamic and engaging experience.
We’ll keep it playful yet straightforward, using HTML to structure the content, CSS for styling, and JavaScript to handle the scrolling animation.
Let’s dive into building the “Scroll Drive All The Things” effect. Whether you’re a beginner or an experienced developer, this project offers a fun way to experiment with scroll animations and create an immersive user experience.
Let’s drive all the things with the scroll!
HTML :
This HTML file creates a list of cards, each representing an HTML element. The cards are styled using CSS classes defined in the linked style.css file. Each card displays the name of an HTML element, and there’s a corresponding CSS class for each card to control its appearance.

CSS :
This CSS code imports styles for a design system and a demo layer. It defines keyframes for a slide-fade-in animation. In the demo layer, it sets up styles for cards, including grid layout, background, shadows, and spacing. Cards are dynamically sized and positioned based on their order.

This code creates a sparkling effect on a webpage. It generates stars that twinkle and glow when you move your mouse or touch the screen. It sets up initial variables and utility functions, then handles mouse and touch events to create stars and glowing effects accordingly.

Throughout this project, we’ve learned how to manipulate elements on the screen in response to the user’s scrolling actions, giving the impression of driving all the content. By combining HTML for structure, CSS for styling, and JavaScript for scroll animation, we’ve crafted an immersive and engaging user experience.
