IconVault's CSS Transition Generator builds buttery CSS transitions with a visual editor. Choose the property to animate, set duration and delay, pick a timing function from presets like ease and ease-in-out, or draw your own cubic-bezier curve with sliders for Spring, Overshoot, Smooth and Snap feels. A live demo shows exactly how your transition behaves on hover or click before you ship it.

Everything runs 100% in your browser with no sign-up and nothing uploaded. Copy the finished transition line in one click, reuse it for buttons, menus, cards and modals, and tweak the curve until the motion feels right. It is free to use and the output is plain, standards-based CSS that works in every modern browser.
