Frequently Asked Questions


            

                

                    What is CSS animation and how do keyframes work?
                

                

                    
CSS animations allow you to gradually change CSS properties over time using @keyframes rules. Keyframes define the animation's stages at specific percentages (0% to 100%), with each keyframe specifying different CSS property values. The browser automatically interpolates between these keyframes to create smooth transitions. For example, you can set different positions, colors, or transforms at 0%, 50%, and 100% to create complex motion effects.

                

            


            

                

                    What are the best CSS animation timing functions?
                

                

                    
CSS offers several timing functions: ease (default, starts slow, speeds up, ends slow), linear (constant speed), ease-in (starts slow), ease-out (ends slow), ease-in-out (slow start and end), and cubic-bezier for custom curves. Choose based on the desired feel: ease for natural motion, linear for mechanical effects, and custom cubic-bezier for unique animations. Our bezier editor lets you visually design custom timing curves for precise control over animation pacing.

                

            


            

                

                    How do I optimize CSS animations for performance?
                

                

                    
For optimal performance, animate only transform and opacity properties, which are GPU-accelerated and don't trigger repaints. Avoid animating properties like width, height, or margin that cause layout recalculations. Use will-change sparingly to hint at upcoming animations, keep animation durations reasonable (200-500ms for UI), and test on lower-end devices. Our generator focuses on transform-based animations for best performance while maintaining visual appeal.
