PropTypeDefaultDescription
propsnull—CompareSliderDemo declares no props. Its rendered JSX uses CompareSlider with defaultValue={50}, className, and nested CompareSliderBefore, CompareSliderAfter, and CompareSliderHandle components.
Accessibility
- Use meaningful, distinct alt text for the before and after images; the demo uses "Before" and "After".
- Ensure the comparison handle exposes an accessible name and keyboard interaction through the underlying compare-slider component.
- Do not rely on grayscale or visual position alone to communicate the difference; provide descriptive alternative text or surrounding context.
- Keep sufficient contrast between the handle, divider, and image content, especially when replacing the demo imagery.
