CSS Time Travel is a new approach to handling animations that allows interfaces to move back in time through historical states.
The technique uses CSS state machines, @keyframes, and class toggling to create directional, reversible, and context-aware transitions between UI states.
It enables components to have unique animations for different states and to move both forward and backward in time while playing the correct animations each way.
CSS Time Travel teaches developers to create logic-rich animations that behave like intelligent flows, making UIs feel more alive and responsive.
