Split-screen comparison

Make it fit your project.

Build a ten-second comparison with two equally sized panels and explicit labels. Hold the comparison for four seconds, move a divider to emphasize the selected state, then expand that state using a continuous crop. Keep labels outside the moving mask until the expansion completes.

Build and check.

1. Confirm the supplied content, target environment, and required assets before implementing.
2. Build a ten-second comparison with two equally sized panels and explicit labels. Hold the comparison for four seconds, move a divider to emphasize the selected state, then expand that state using a continuous crop. Keep labels outside the moving mask until the expansion completes.
3. Expose seek(t) so frames can be inspected deterministically; add play, pause, replay, and a reduced-motion still.
4. Inspect the opening, midpoint, and final state at desktop and mobile sizes; report any dependency or output limitation.

Know the limits.

• Avoid fabricated before-and-after claims; supplied examples need equivalent scale and framing.
• The prompt guides a coding agent; output quality depends on its implementation and review.
