Create CSS keyframe animations with visual precision using a complete animation builder with live preview, timing controls, and easing curve customization. CSS animations bring web pages to life with smooth transitions, engaging motion effects, and interactive feedback that CSS transitions alone cannot achieve. This tool eliminates complex @keyframes syntax by providing a visual editor where you select animation presets or create custom animations from scratch. Add and edit keyframes at specific points during the animation cycle, define the properties that change (position, opacity, scale, rotation, etc.), and preview changes instantly. Adjust timing parameters including duration, delay, iteration count, and easing functions from linear to complex cubic-bezier curves. The tool generates production-ready CSS that works in all modern browsers. Includes multiple animation presets for common effects like fade-ins, slides, bounces, and spins.
Create engaging animations for buttons, cards, forms, and other UI elements that provide visual feedback.
Design rotating spinners, progress bars, and skeleton screens that indicate loading states visually.
Create smooth animations triggered by hovering or clicking elements to enhance interactivity.
Design fade-in, slide, and other transitions that make page changes feel smooth and polished.
Create animations that trigger when elements scroll into view, engaging users as they explore content.
Design animated backgrounds, gradients, and decorative elements that run continuously or on interaction.
CSS animations and transitions represent two distinct but complementary approaches to adding motion to web interfaces. CSS transitions provide simple A-to-B property changes triggered by state changes (like hover or class additions), while CSS keyframe animations defined with @keyframes allow multi-step sequences that can run automatically, loop infinitely, and alternate direction. The @keyframes rule defines named animation sequences with waypoints specified as percentages (0% to 100%, or using the "from" and "to" keywords), where each waypoint declares the CSS property values at that point in the animation timeline.
Easing functions are the mathematical curves that control the rate of change during an animation, transforming what would otherwise be mechanical linear motion into natural, organic movement. CSS provides several built-in easing keywords: linear (constant speed), ease (slow start, fast middle, slow end), ease-in (slow start, fast end), ease-out (fast start, slow end), and ease-in-out (slow start and end). The cubic-bezier() function provides complete control over the easing curve through four control points that define a cubic Bezier curve mapping time progress to animation progress. Notably, the y-values of control points can exceed 0 and 1, creating overshoot effects where the animation goes beyond its target value before settling, simulating physical properties like spring tension or bounce.
GPU acceleration is a critical performance consideration for CSS animations. Modern browsers can offload certain CSS property animations to the GPU compositor thread, which operates independently of the main JavaScript thread. Properties that can be GPU-composited include transform (translate, scale, rotate), opacity, and filter. Animating these properties is significantly cheaper than animating layout-triggering properties (width, height, margin, padding) or paint-triggering properties (color, background, box-shadow), which force the browser to recalculate layout or repaint elements. The will-change CSS property hints to the browser that an element will be animated, allowing it to pre-promote the element to its own compositor layer for smoother animation.
The CSS animation shorthand property combines eight individual properties: animation-name (the @keyframes reference), animation-duration, animation-timing-function (easing), animation-delay, animation-iteration-count (number or infinite), animation-direction (normal, reverse, alternate, alternate-reverse), animation-fill-mode (how styles apply before and after the animation), and animation-play-state (running or paused). The animation-fill-mode property is particularly important: "forwards" retains the final keyframe styles after the animation ends, "backwards" applies the first keyframe styles during the delay period, and "both" combines these behaviors. Multiple animations can be applied to a single element using comma-separated values, enabling complex compositions like simultaneous fade-in, slide-up, and rotation effects.
CSS keyframe animations define a sequence of styles at specific points during an animation cycle using @keyframes. Unlike transitions, they can have multiple intermediate steps and run automatically without user interaction.
Easing functions control the speed curve of an animation. Linear moves at constant speed, ease-in starts slow, ease-out ends slow, and ease-in-out does both. Custom cubic-bezier curves offer precise control.
Yes, set the animation iteration count to infinite. This is commonly used for loading spinners, pulsing effects, and background animations that should run continuously.
CSS allows multiple animations separated by commas in the animation property. For example, you can combine a fade-in with a slide-up by applying both animation names with independent durations and delays.
