How to Use This Cubic Bezier Visualizer - Interactive CSS Animation Easing Tool

How to Use the Cubic Bezier Visualizer:

Select from preset easing functions (ease, ease-in-out, etc.) or choose 'Custom' for manual values
For custom curves, enter four comma-separated values: x1,y1,x2,y2 (e.g., 0.25,0.1,0.25,1)
Enable live animation preview to see how the curve affects animation timing
Click "Generate Curve" to create the interactive visualization and CSS code
Experiment with the visual curve editor to fine-tune control points
Copy the generated CSS cubic-bezier code for use in your projects

Pro Tips: X values must be between 0-1, but Y values can exceed this range for bouncing effects. Use negative Y values for anticipation and values >1 for overshoot effects!

How It Works

Cubic Bezier Curve Technology:

Our visualizer uses advanced mathematical modeling to render and animate cubic bezier curves:

Curve Mathematics: Implements true cubic Bezier curve equations with P0=(0,0), P3=(1,1) endpoints
Control Point System: Two adjustable control points (P1 and P2) define curve shape and timing
Canvas Rendering: HTML5 Canvas API draws real-time curve visualization with precise coordinates
Animation Engine: Live preview shows actual easing effect on moving elements
CSS Generation: Outputs standard CSS cubic-bezier() function for cross-browser compatibility

Technical Note: The visualizer maintains mathematical precision while providing intuitive visual feedback, making complex easing curves accessible to designers and developers.

Frequently Asked Questions

What are the four values in a cubic-bezier curve?

The four values represent control point coordinates: cubic-bezier(x1, y1, x2, y2). The first control point (x1,y1) affects the curve's start behavior, the second (x2,y2) affects the end. X values must be between 0-1, but Y values can exceed this range for bouncing effects.

How do I use cubic-bezier values in CSS animations?

Apply cubic-bezier to animation-timing-function or transition-timing-function properties: 'animation-timing-function: cubic-bezier(0.25, 0.1, 0.25, 1);' or use it in shorthand: 'transition: all 0.3s cubic-bezier(0.68, -0.55, 0.265, 1.55);' for smooth transitions.

What's the difference between ease presets and custom cubic-bezier curves?

CSS presets like 'ease' and 'ease-in-out' are predefined cubic-bezier curves (ease = cubic-bezier(0.25, 0.1, 0.25, 1)). Custom curves give you precise control over acceleration and deceleration, allowing for unique effects like anticipation or overshoot that presets can't provide.

Can Y values in cubic-bezier go below 0 or above 1?

Yes! While X values must stay between 0-1 (representing time), Y values can exceed this range. Negative Y values create anticipation effects (element moves backward before forward), and Y values >1 create overshoot effects (element goes past target before settling).

Which browsers support cubic-bezier CSS functions?

cubic-bezier() is supported by all modern browsers including Chrome, Firefox, Safari, and Edge. It's part of CSS3 specifications and works reliably across desktop and mobile browsers. For IE9-10 support, consider fallbacks using standard keywords like 'ease' or 'linear'.
