3 CSS Scroll Effects
A CSS scroll effect is an animation that is directly linked to a user's scroll position on a webpage, created using pure CSS without any JavaScript, making a webpage feel more interactive and dynamic. The key to modern CSS scroll effects is the Scroll-driven Animations specification, which allows you to control the progress of a CSS animation based on the scroll position of a container using the animation-timeline property. This is a declarative and highly performant alternative to traditional JavaScript-based scroll listeners. With these CSS features, you can create popular effects like a scroll progress bar, revealing elements that fade or slide into view, and parallax-like effects. This collection showcases a variety of scroll-triggered animations built with modern, pure CSS, including scroll progress indicators and elements that animate as they appear on screen, helping you learn to create highly performant, scroll-based interactions without writing any JavaScript.
Scroll-Synced Progress & Editable Heading
An interactive, scroll-driven UI component that combines a live progress indicator with an editable headline. As the user scrolls through the page, a percentage tracker updates in real time, visually synchronized with the movement of the heading. The heading is fully contenteditable, allowing direct inline editing while retaining animated scroll effects.
Scroll-Driven Big Cat Gallery
A full-screen, scroll-driven gallery showcasing majestic big cats with their scientific names and high-resolution photos. Each cat section features sticky positioning, smooth scroll animations, and 3D-like transitions, making images and headers slide and scale dynamically as the user scrolls. Subtle clipping, translate, and opacity effects enhance depth, while CSS custom properties track scroll progress.
Scroll-Driven Horizontal Image Gallery
Scroll-Driven Horizontal Image Gallery creates a dynamic scrolling experience where images move horizontally as you scroll vertically through the page. Each image is perfectly sized and spaced for smooth visual flow, while sticky headers guide the user with engaging prompts. The gallery uses modern CSS features like animation-timeline for scroll-driven animations, gradients for subtle progress indication, and sticky positioning to keep content visible during scrolling.
