CSS Easing and Animation Visualizer

· Last updated：2026-06-21

Visualize a CSS cubic-bezier easing curve, preview it live on position/opacity/scale, pick presets, and export copy-ready CSS

Details

What this tool helps you do

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.

Overview

The CSS Easing and Animation Visualizer lets you design, test, and export custom cubic-bezier timing functions and presets. By plotting the easing curve alongside live previews of translation, opacity, and scale, you can fine-tune animation durations and delays before copying production-ready CSS transition or keyframe code.

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

  1. 1Input a custom cubic-bezier coordinate or select one of the built-in presets like ease-in-out, snappy, or ease-out-back.
  2. 2Adjust the animation duration and delay parameters in milliseconds to control the timing of the transition.
  3. 3Review the generated SVG easing curve and watch the live preview animate across translateX, opacity, and scale properties.
  4. 4Copy 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.

Examples

1. Designing a Snappy Button Pop Animation

UI Designer

Background

A designer wants to add a playful, bouncy scale-up effect to a primary call-to-action button when hovered.

Problem

Standard CSS ease-out feels too flat, and manually guessing cubic-bezier coordinates for a bounce is tedious.

How to use

Select the 'ease-out-back' preset, set the duration to 600ms, and observe the scale preview to verify the bounce intensity.

easing: cubic-bezier(0.34, 1.56, 0.64, 1), duration: 600ms

Outcome

The designer copies the generated CSS transition code, achieving a perfect spring-back button animation.

2. Creating a Smooth Fade-In for Image Cards

Frontend Developer

Background

A developer needs to animate a grid of product cards fading in sequentially without looking abrupt.

Problem

Linear transitions look robotic, while standard ease-in starts too slowly for fast-loading content.

How to use

Input a custom cubic-bezier curve or select 'ease-out-expo', set a 100ms delay, and preview the opacity transition.

FAQ

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.
