Frequently Asked Questions
How do I create a CSS animation?
Define keyframes with start and end states, set duration, timing function, and iteration count. The generator produces ready-to-use CSS. Example: a fade-in animation uses @keyframes fadeIn { from { opacity: 0 } to { opacity: 1 } }.
What CSS animation properties can I customize?
Duration (how long), delay (when to start), timing-function (ease, linear, cubic-bezier), iteration-count (how many times), direction (normal, reverse, alternate), and fill-mode (forwards, backwards, both). The generator provides visual controls for each.
What is a cubic-bezier timing function?
Cubic-bezier defines custom acceleration curves with four control points: cubic-bezier(x1,y1,x2,y2). Common presets: ease (0.25,0.1,0.25,1), ease-in (0.42,0,1,1), ease-out (0,0,0.58,1). The generator includes a visual curve editor.
How do I create a multi-step animation?
Use percentage keyframes: @keyframes bounce { 0% { transform: translateY(0) } 50% { transform: translateY(-30px) } 100% { transform: translateY(0) } }. The generator lets you add unlimited keyframe steps with visual preview.
Do CSS animations affect performance?
Animations on transform and opacity are GPU-accelerated and performant. Avoid animating layout properties (width, height, margin, padding) as they trigger reflow. Use will-change: transform to hint the browser for optimization.
