# CSS Easing and Animation Visualizer Visualize a CSS cubic-bezier easing curve, preview it live on position/opacity/scale, pick presets, and export copy-ready CSS > Canonical page: https://elysiatools.com/en/tools/css-easing-visualizer - **Category:** Design - **Keywords:** css easing, cubic bezier, animation, transition, timing function, ease, ease-in, ease-out, bezier curve, animation timing, keyframes, motion design ## Overview Tune CSS animation timing: enter a cubic-bezier or pick a preset, see the easing curve (progress vs time) with control points, watch live previews on translateX/opacity/scale, and copy ready-to-use transition and keyframes CSS. The Bézier solver maps time→progress exactly like browsers. ## Inputs - **Easing Input** (text): cubic-bezier(0.34, 1.56, 0.64, 1) · ease-out · linear - **Preset** (select) - **Duration (ms)** (number) - **Delay (ms)** (number) ## When to use - When designing custom UI transitions that require precise timing curves beyond standard browser defaults. - When debugging bouncy or overshooting animations to ensure they do not cause unexpected layout shifts. - When generating copy-ready CSS transition or keyframe code for web animations. ## How it works - Input a custom cubic-bezier coordinate or select one of the built-in presets like ease-in-out, snappy, or ease-out-back. - Adjust the animation duration and delay parameters in milliseconds to control the timing of the transition. - Review the generated SVG easing curve and watch the live preview animate across translateX, opacity, and scale properties. - Copy the generated CSS transition or keyframe code directly into your stylesheet. ## Use cases - Creating a snappy, spring-like bounce effect for interactive buttons and modal entries. - Fine-tuning smooth, gradual fade-ins for image galleries and page transitions. - Prototyping complex UI motion paths by visualizing progress-over-time curves before writing code. ## Frequently asked questions ### What is a cubic-bezier curve? It is a mathematical curve defined by four control points that determines the speed of a CSS transition over time. ### How does the live preview work? It applies your selected easing curve, duration, and delay to real-time CSS animations of position (translateX), opacity, and scale. ### What are overshooting curves? These are curves where values go below 0 or above 1, creating a bounce effect that may cause layout shifts. ### Can I copy keyframe animations? Yes, the tool generates both standard CSS transition properties and keyframe-compatible CSS code. ### How accurate is the curve solver? It uses a Newton-Raphson solver with bisection fallback to map time to progress exactly as modern web browsers do. ## Related tools - [Color Space Converter](https://elysiatools.com/en/tools/color-space-converter): Convert a color between HEX, RGB, HSL, CIELAB, and Display-P3 with CSS-ready output and gamut checks. - [CMYK Color Converter](https://elysiatools.com/en/tools/cmyk-converter): Convert HEX, RGB, HSL, and CMYK colors into all four representations. - [OKLCH Color Converter](https://elysiatools.com/en/tools/oklch-color-converter): Convert bidirectionally between HEX, RGB, HSL, OKLCH and Display-P3 using CSS Color 4 math, with gamut checks and out-of-gamut clipping suggestions - [CSS Animation Generator](https://elysiatools.com/en/tools/animation-generator): Generate CSS animation keyframes and properties - [Color Palette Extractor from Image URL](https://elysiatools.com/en/tools/color-palette-extractor-from-image-url): Fetch a remote image URL, extract dominant colors, export code-ready palette files, and review contrast ratios - [ECharts Theme Token Extractor](https://elysiatools.com/en/tools/echarts-theme-token-extractor): Extract design tokens — colors, numbers, font sizes and strings — from an ECharts theme JSON and export them straight into your design system.
