Examples
Before and after comparison
A drag-controlled image comparison with the default handle.
before-and-after-comparison.tsx
import { Comparison, ComparisonHandle, ComparisonItem,} from "@/components/kibo-ui/comparison";<Comparison className="aspect-video" mode="drag"> <ComparisonItem position="left"> <img src="/after.jpg" alt="After renovation" className="h-full w-full object-cover" /> </ComparisonItem> <ComparisonItem position="right"> <img src="/before.jpg" alt="Before renovation" className="h-full w-full object-cover" /> </ComparisonItem> <ComparisonHandle /></Comparison>Hover comparison
A comparison whose divider follows pointer or touch movement without requiring a drag.
hover-comparison.tsx
import { Comparison, ComparisonHandle, ComparisonItem,} from "@/components/kibo-ui/comparison";<Comparison className="aspect-[4/3]" mode="hover"> <ComparisonItem position="left"> <img src="/rendered.jpg" alt="Rendered room" className="h-full w-full object-cover" /> </ComparisonItem> <ComparisonItem position="right"> <img src="/photograph.jpg" alt="Photographed room" className="h-full w-full object-cover" /> </ComparisonItem> <ComparisonHandle /></Comparison>Custom comparison handle
A comparison using custom handle content instead of the built-in divider and grip icon.
custom-comparison-handle.tsx
import { Comparison, ComparisonHandle, ComparisonItem,} from "@/components/kibo-ui/comparison";<Comparison className="aspect-video"> <ComparisonItem position="left"> <img src="/new-design.png" alt="New design" className="h-full w-full object-cover" /> </ComparisonItem> <ComparisonItem position="right"> <img src="/old-design.png" alt="Old design" className="h-full w-full object-cover" /> </ComparisonItem> <ComparisonHandle className="w-12"> <div className="rounded-full bg-primary px-2 py-1 text-xs text-primary-foreground"> Compare </div> </ComparisonHandle></Comparison>API reference
PropTypeDefaultDescription
ComparisonHTMLAttributes<HTMLDivElement> & { mode?: "hover" | "drag"; onDragStart?: () => void; onDragEnd?: () => void }—Root comparison container. Accepts all standard `div` HTML attributes. `mode` defaults to `"drag"`; `"drag"` updates the slider while pressed, while `"hover"` updates it during pointer or touch movement. `onDragStart` and `onDragEnd` run only in drag mode.
ComparisonItemComponentProps<typeof motion.div> & { position: "left" | "right" }—A required child layer rendered as an absolutely positioned Motion `div`. `position` determines the clip direction: `"left"` clips from the left slider position, and `"right"` clips from the right. It accepts all Motion `div` props.
ComparisonHandleComponentProps<typeof motion.div> & { children?: ReactNode }—The positioned slider handle rendered as a Motion `div`. It accepts all Motion `div` props and optional React children. Without children, it renders the divider and the default grip icon in drag mode.
Accessibility
- The root uses `role="slider"`, `tabIndex={0}`, and exposes `aria-valuemin="0"`, `aria-valuemax="100"`, and the current percentage through `aria-valuenow`.
- The component does not implement keyboard handlers, so keyboard users cannot currently change the slider position with arrow keys.
- The root has the accessible label `Comparison slider`; provide additional surrounding context when multiple comparisons appear on the same page.
- Each `ComparisonItem` is marked `aria-hidden="true"` and `role="img"`; meaningful image descriptions should be supplied by the surrounding comparison context or visually hidden content.
- The handle is marked `aria-hidden="true"` and `role="presentation"`, so it is decorative rather than an additional interactive control.
