What's Included

Everything you get with our CSS Animations

CSS Animation Library

Complete set of CSS keyframe animations and transitions for all your UI components, built with custom properties for easy customization

Timing Token System

Documented CSS custom properties for duration values, easing curves, and delay sequences that ensure consistent motion across your product

Performance Validation Report

Chrome DevTools profiling confirming compositor-thread execution, 60fps consistency, and zero layout thrashing for every animation

Our CSS Animation Process

1

Motion Audit & Planning

We review your interface components and identify every element that benefits from CSS animation: buttons, cards, navigation, modals, tooltips, form elements, and content sections. We map the animation type each element needs.

2

Timing & Easing Design

We design custom timing curves and duration values for each animation category. Quick feedback animations (150-200ms) for buttons and toggles. Medium transitions (250-350ms) for content reveals. Longer sequences (400-600ms) for page-level choreography.

3

CSS Implementation

We build each animation using CSS custom properties for timing tokens, @keyframes for multi-step sequences, and transition shorthand for state changes. All values are design-system-ready and documented.

4

Performance Validation

We profile every animation in Chrome DevTools to confirm compositor-thread execution, verify 60fps consistency, test prefers-reduced-motion fallbacks, and validate that no animation triggers layout thrashing.

Key Benefits

Zero JavaScript overhead

CSS animations run entirely in the browser's rendering engine. No animation libraries to download, parse, and execute. No JavaScript runtime cost. No bundle size impact. Your animations load instantly because the browser already has everything it needs to run them.

Hardware-accelerated performance

Transform and opacity animations run on the GPU compositor thread, completely separate from your main thread. JavaScript execution, DOM manipulation, and other expensive operations cannot interfere with CSS animation frame rates. You get guaranteed 60fps smoothness.

Universal browser support

CSS animations and transitions have been supported by every major browser for over a decade. No polyfills, no fallbacks, no compatibility testing. Write once, and it works everywhere: Chrome, Firefox, Safari, Edge, iOS Safari, and Android Chrome.

Frequently Asked Questions

When should we use CSS animations vs JavaScript animations?

Use CSS for state transitions (hover, focus, active), entrance and exit animations, and any motion that runs on transform or opacity. Use JavaScript only when you need to animate values CSS cannot access (scroll position, complex physics, data-driven values) or when animation needs to respond to real-time input. In practice, 80-90% of UI animations should be pure CSS.

How do CSS animations affect Core Web Vitals?

CSS animations that use transform and opacity have zero impact on Cumulative Layout Shift (CLS), zero impact on Interaction to Next Paint (INP), and zero impact on Largest Contentful Paint (LCP). They run on the compositor thread and never trigger layout recalculations. The only risk is animating properties like width, height, or margin, which we never do.

Can CSS animations be interactive?

Yes. CSS animations respond to pseudo-classes like :hover, :focus, :active, and :checked without any JavaScript. For more complex interactions, a single line of JavaScript to toggle a CSS class can trigger elaborate multi-step animations. The animation logic stays in CSS where it is most performant.

Do CSS animations work with our existing component library?

Absolutely. CSS animations are an enhancement layer added to your existing components through classes and custom properties. Your component structure, props, and logic stay exactly the same. We add animation styles that activate on state changes your components already handle.
