30+ CSS cubic-bezier Examples
Linear motion feels artificial. This updated collection of CSS cubic-bezier examples removes the robotic barrier of default timing functions, allowing developers to craft custom easing curves that mimic real-world physics. Utilizing these curated snippets ensures animations feel organic, tactile, and intentional, bridging the gap between static states and fluid interaction.
Technically, the cubic-bezier() function defines a timing curve using four control points (P0 to P3). This mathematical precision allows for effects like anticipation, overshoot, and bounce — all calculated natively by the browser. By defining these curves, animations leverage strict hardware acceleration, targeting transform and opacity to maintain a locked 60fps performance on the compositor thread. The HTML remains strictly semantic, as the motion physics are handled entirely by the UI design layer.
Every free demo in this library is fully responsive and cross-browser compatible. Users can instantly download the raw code or fork an updated animation curve on CodePen. These assets are optimized for performance, ensuring a fast, frictionless experience across all modern design systems.
Examples

Neumorphic Analog Clock with Springy Hands
An interactive analog clock featuring a rich crimson neumorphic face and springy tick transitions. Built with SCSS and vanilla JavaScript, the script queries local system time and translates hours, minutes, and seconds into corresponding geometric degrees. A custom cubic-bezier timing function adds an organic, elastic bounce to each ticking hand.
See the Pen Neumorphic Analog Clock with Springy Hands.

Bouncy Bear Theme Toggle Switch
Bouncy Bear Theme Toggle Switch relies on a clean, accessible HTML <button> to toggle an aria-pressed state, initiating a complex visual narrative that shifts between an aviator bear in light mode and an astronaut bear in dark mode. The animation utilizes modern CSS layout techniques including container-type queries, separate translate declarations, and a heavy-backwards cubic-bezier(.4,-0.3,.6,1.3) curve to achieve physical bounce. While structurally robust, the sheer volume of concurrently transitioning inline SVG paths and scaling stars can generate intensive layout recalculation spikes unless elements are actively isolated via hardware-promoted layers.
See the Pen Bouncy Bear Theme Toggle Switch.

Micro-Animated SVG Icon Bar
Static icons are dead pixels; they occupy space but offer no soul. We believe that every interaction — no matter how small — is an opportunity to delight. This navigation bar transforms the mundane act of switching tabs into a tactile event. By embedding the animation logic directly into the SVG structure, we create a system that feels organic, responsive, and deeply crafted. It is not just about showing the user where they are; it is about rewarding them for arriving there.
See the Pen Micro-Animated SVG Icon Bar.

Tectonic Stacked Tooltip Button
This Tectonic Stacked Tooltip creates a sophisticated, industrial-grade micro-interaction. Instead of a simple fade-in, the tooltip constructs itself from multiple sliding “plates” (slabs) that expand outward upon hovering. With its dark aesthetic, noise textures, and precise easing, it fits perfectly into sci-fi games, technical dashboards, or brutalist web designs. (Requires: Google Fonts (JetBrains Mono))
See the Pen Tectonic Stacked Tooltip Button.

CSS Flip-Disc Mechanical Checkbox
This Flip-Disc Mechanical Checkbox brings the satisfying, tactile physics of old-school airport information boards to the web. Instead of a simple tick, selecting an item triggers a 3D rotation of a mechanical disc, flipping it from a dark, inactive side to a glowing orange active side. This creates a high-contrast, industrial aesthetic perfect for system dashboards or retro-themed interfaces.
See the Pen CSS Flip-Disc Mechanical Checkbox .

Extreme Hover with HTML and CSS

See the Pen Segmented/Pill Radio Input.

Form Wave Animation
Clicking the input field doesn’t just slide the label up; instead, it playfully ‘hops’ letter by letter, adding a micro-interaction that brings the form to life.
See the Pen Form Wave Animation.

Rotating Navigation
An interactive card stack that fans out into a deck-like display upon toggling. JavaScript handles the state transition by toggling classes, triggering CSS cubic-bezier transitions that rotate and translate the cards from a bottom-center origin, creating a smooth, elastic opening animation accompanied by a rotating navigation button.
See the Pen Rotating Navigation.

Sliding Dot Pagination
This pagination component’s core logic is managed in SCSS, where the .active class (toggled by a minimal JavaScript snippet) triggers a transform: translateX() on a .pagination-current element, creating a fluid “sliding dot” effect. The user experience is further enhanced by a series of polished micro-interactions on the :hover and :active states, which use transform transitions with custom cubic-bezier timing functions to create subtle scaling and “squash and stretch” animations.
See the Pen Sliding Dot Pagination.

Colorful Popup Hamburger Menu
A “fan-out” circular menu in pure CSS, where the hamburger icon animation and cascading item reveal are triggered by the “checkbox hack.” The reveal effect uses transform: translate3d() with transition-delay, and the animation’s liveliness is achieved through complex cubic-bezier curves, giving it a natural “elastic” bounce.
See the Pen Colorful Popup Hamburger Menu.
