Comparison reveal

A draggable before-and-after surface with a keyboard-operable divider.

Open in Gamma

What to study

  • Drag the divider or focus it and use arrow keys; Home and End reach either edge.
  • Provide equivalent sized layers so the split describes the same scene.
  • The artwork is a Gamma demo fixture; supply your own React content in production.
