Frequently Asked Questions

What is a CSS keyframe animation?

A CSS keyframe animation defines intermediate steps in a transition using @keyframes rules. You specify property values at different percentage points (0%, 50%, 100%), and the browser interpolates between them. This gives you full control over timing, easing, and multi-step sequences without JavaScript.

What is the difference between CSS transitions and animations?

Transitions animate a property change triggered by a state change (e.g. :hover). Animations run independently via @keyframes and can loop, reverse, and have multiple steps. Tip: use transitions for simple hover/focus effects and animations for looping sequences, loading spinners, or attention-grabbing UI elements.

How do I make CSS animations perform well?

Stick to animating transform and opacity — these properties are GPU-accelerated and don't trigger layout recalculations. Avoid animating width, height, top, left, margin, or padding as they cause expensive reflows. Tip: use will-change: transform on animated elements to hint the browser to optimize them.

How do I use a CSS animation with Tailwind CSS?

Tailwind provides animate-spin, animate-ping, animate-pulse, and animate-bounce out of the box. For custom animations, define @keyframes in your CSS file and add the animation to tailwind.config under theme.extend.animation and theme.extend.keyframes. This generator outputs both the raw CSS and Framer Motion code.

Can I combine multiple CSS animations on one element?

Yes, list them comma-separated: animation: fadeIn 0.3s ease, slideUp 0.5s ease-out. Each animation runs independently with its own duration and timing. Tip: use animation-delay on subsequent animations to create staggered sequences.
