How It Works

1

Choose a Preset or Build Custom

Start with a preset animation like fade, slide, or bounce, or build your own from scratch.

2

Edit Keyframes

Add, remove, and modify keyframes with transform and opacity values at specific percentages.

3

Copy CSS

Copy the complete @keyframes rule and animation property for your stylesheet.

Frequently Asked Questions

What are CSS keyframe animations?
CSS @keyframes animations define a sequence of styles that an element transitions through over time. You specify the styles at various points (0%, 50%, 100%) and the browser interpolates between them.
What timing functions are available?
Common timing functions include ease (slow start and end), linear (constant speed), ease-in (slow start), ease-out (slow end), and ease-in-out (slow start and end). You can also use cubic-bezier for custom curves.
What does animation-direction do?
animation-direction controls whether the animation plays forward, backward, or alternates. "alternate" plays forward then backward, creating a yo-yo effect.
Can I combine multiple animations?
Yes, you can apply multiple animations to one element by separating them with commas in the animation shorthand property.
How do I make animations accessible?
Use the prefers-reduced-motion media query to disable or reduce animations for users who have requested reduced motion in their system settings.

About Animation Gen

What this tool does

Developer and design tools include CSS generators (gradients, shadows, glassmorphism), code playgrounds, color pickers, responsive previews, and reference charts for HTML tags, HTTP methods, and keyboard shortcuts.

Why use this tool

Front-end development involves constant context switching between code and visual output. Having generators and references in a single browser tab speeds up prototyping and reduces the need to search through documentation sites.

How it works

Each tool provides an interactive UI: you tweak parameters (colors, radii, durations), and the tool generates the corresponding CSS, HTML, or SVG code in real time. Copy the snippet directly into your project.

Pro tip

Use the CSS variable output option when available. It makes your generated code theme-friendly and easier to maintain across a design system.
