20+ JavaScript Hero Effects
Hero sections are the first impression of a site — adding JavaScript-powered effects can make them unforgettable. This collection of JavaScript hero effects features animated headlines, scroll-triggered reveals, video backgrounds, particle overlays, and interactive canvases for bold, dynamic entrances.
Examples

PixiJS Displacement Ripple Zoom
This is a PixiJS Displacement Ripple Zoom. It transforms a static background image into an interactive, liquid-like surface that expands outward from the user’s cursor upon clicking. Its function is to serve as a dramatic, cinematic entrance animation for hero sections or landing pages, shifting visual focus while seamlessly introducing secondary UI elements. (Requires: pixi-js, gsap-js, SplitText.js)
See the Pen PixiJS Displacement Ripple Zoom.

Wireframe Ocean Vector Waves
This is a Wireframe Ocean Vector Waves background. It renders multiple layered vector paths using mathematical sine functions to simulate a rolling sea. Its function is to create a dynamic, highly illustrative hero section, integrating static text behind a moving fluid layer to establish a strong sense of depth. (Requires: paper.js)
See the Pen Wireframe Ocean Vector Waves.

Halloween Countdown Hero Section
This is a Halloween Countdown Hero Section. It combines a functional date countdown with thematic, highly kinetic visual elements like dropping spiders and cursor-tracking skull eyes. Its function is to immediately immerse users in a seasonal campaign while driving urgency toward a specific deadline.
See the Pen Halloween Countdown Hero Section.

Cinematic Masked Video Hero
This is a Cinematic Masked Video Hero. It layers solid and outlined typography over an SVG-clipped video element to create optical depth. Its function is to immediately capture attention on landing, breaking away from standard rectangular layouts through organic polygon masking and staggered motion. (Requires: gsap-js)
See the Pen Cinematic Masked Video Hero.

Reveal Animated Hero Slider
This is a Reveal Animated Hero Slider. It cycles through prominent featured content using synchronized transitions. Its function is to capture user attention instantly, employing staggered typography reveals and a sweeping geometric mask to introduce new visual assets without jarring cuts.
See the Pen Reveal Animated Hero Slider.

Lenis Smooth Scroll & GSAP Page
This is a Lenis Smooth Scroll & GSAP Page. It transforms a standard one-page website into a high-end, cinematic scrolling experience. Its function is to provide an exceptionally fluid and responsive interface by replacing native “jumpy” browser scrolling with the physics-based smoothness of Lenis, while using GSAP’s ScrollTrigger to orchestrate a series of staggered animations that reveal content as the user navigates down the page. (Requires: GSAP, Lenis, ScrollTrigger)
See the Pen Lenis Smooth Scroll & GSAP Page.

Animated Fruity Product Showcase
This is an Animated Fruity Product Showcase. It acts as a high-impact hero section for a product landing page. Its function is to create a sense of dynamic energy through synchronized GSAP animations, where product imagery “falls” into view, titles update with staggered transitions, and ripple-wave effects surround the navigation buttons. (Requires: GSAP)
See the Pen Animated Fruity Product Showcase.

Mouse-Driven Split Reveal
Static content is a relic. We don’t just want to show information; we want the user to uncover it. This component transforms the cursor into a tool of discovery, creating a tactile connection between the user and the interface. By removing the friction of clicking or dragging handles, we achieve a fluidity that feels less like software and more like a physical extension of the hand. It is simple, unapologetic, and immediate.
See the Pen Mouse-Driven Split Reveal.

Cinematic Hero Section In-View Animation
A cinematic hero section for a museum website featuring a synchronized text reveal animation powered by GSAP timelines and CustomEase. The layout utilizes fluid typography based on viewport width and intricate DOM segmentation, allowing syllables and UI elements to slide seamlessly into view over a looping background video.
See the Pen Cinematic Hero Section In-View Animation.

Illustration Parallax on Hero Section
A parallax effect with GSAP ScrollTrigger - as the page scrolls, a trigger animates the Y-coordinate of several image layers, creating a sense of depth, with movement smoothness defined by a CustomEase.
See the Pen Illustration Parallax on Hero Section.

Metaballs Hero Section with Three.js
Interactive metaballs brought to life by a custom THREE.js shader, they react to cursor movement and offer a range of presets, making the demo truly responsive and performant.
See the Pen Metaballs Hero Section with Three.js.
