import { CompareSlider, CompareSliderAfter, CompareSliderBefore, CompareSliderHandle,} from "@/registry/bases/radix/ui/compare-slider";export default function Example() { return ( <CompareSlider defaultValue={50} orientation="vertical" className="h-[400px] w-full overflow-hidden rounded-lg border"> <CompareSliderBefore> <img src="/mountain.jpg" alt="Before" className="size-full object-cover" /> </CompareSliderBefore> <CompareSliderAfter> <img src="/mountain-grayscale.jpg" alt="After" className="size-full object-cover grayscale" /> </CompareSliderAfter> <CompareSliderHandle /> </CompareSlider> );}- Compare a color image with a grayscale, edited, or processed version.
- Show before-and-after changes in photography, design, or visual media.
- Use a vertical reveal interaction when users should compare the left and right portions of an image.
- Provide an interactive alternative to placing two large images side by side.
Examples
Color versus grayscale photo
Use the demo's original visual treatment to compare a color photograph with a grayscale version.
color-versus-grayscale-photo.tsx
import { CompareSlider, CompareSliderAfter, CompareSliderBefore, CompareSliderHandle,} from "@/registry/bases/radix/ui/compare-slider";export default function PhotoComparison() { return ( <CompareSlider defaultValue={50} orientation="vertical" className="h-[400px] w-full overflow-hidden rounded-lg border"> <CompareSliderBefore> <img src="/photo-color.jpg" alt="Color photograph" className="size-full object-cover" /> </CompareSliderBefore> <CompareSliderAfter> <img src="/photo-grayscale.jpg" alt="Grayscale photograph" className="size-full object-cover grayscale" /> </CompareSliderAfter> <CompareSliderHandle /> </CompareSlider> );}Original versus edited artwork
Reveal an edited illustration against its original version.
original-versus-edited-artwork.tsx
import { CompareSlider, CompareSliderAfter, CompareSliderBefore, CompareSliderHandle,} from "@/registry/bases/radix/ui/compare-slider";export default function ArtworkComparison() { return ( <CompareSlider defaultValue={35} orientation="vertical" className="h-[500px] w-full overflow-hidden rounded-xl border"> <CompareSliderBefore> <img src="/artwork-original.jpg" alt="Original artwork" className="size-full object-cover" /> </CompareSliderBefore> <CompareSliderAfter> <img src="/artwork-edited.jpg" alt="Edited artwork" className="size-full object-cover" /> </CompareSliderAfter> <CompareSliderHandle /> </CompareSlider> );}Unprocessed versus processed image
Compare an untreated image with a processed version such as a color grade or restoration.
unprocessed-versus-processed-image.tsx
import { CompareSlider, CompareSliderAfter, CompareSliderBefore, CompareSliderHandle,} from "@/registry/bases/radix/ui/compare-slider";export default function ProcessedImageComparison() { return ( <CompareSlider defaultValue={65} orientation="vertical" className="h-[360px] w-full overflow-hidden rounded-lg border"> <CompareSliderBefore> <img src="/image-before.jpg" alt="Image before processing" className="size-full object-cover" /> </CompareSliderBefore> <CompareSliderAfter> <img src="/image-after.jpg" alt="Image after processing" className="size-full object-cover" /> </CompareSliderAfter> <CompareSliderHandle /> </CompareSlider> );}API reference
PropTypeDefaultDescription
propsnull—The `CompareSliderVerticalDemo` example component does not declare any props. The rendered `CompareSlider` receives `defaultValue={50}`, `orientation="vertical"`, and a Tailwind `className`; its child components receive their content through children.
Accessibility
- Both images use descriptive `alt` text identifying the before and after states.
- The comparison handle should remain keyboard-operable through the underlying slider implementation; retain the provided `CompareSliderHandle` rather than replacing it with a decorative element.
- Ensure the before and after image descriptions communicate the meaningful visual difference, not only generic labels such as “Before” and “After.”
- The external Unsplash images should remain available in production or be replaced with locally hosted assets with equivalent alternative text.
