import { Progress } from "@/components/ui/8bit/progress";<Progress value={65} aria-label="Download progress" /><Progress value={45} variant="retro" aria-label="Game installation progress" /><Progress value={80} progressBg="bg-green-500" aria-label="Upload progress" />- Show completion or loading progress in a retro or pixel-art interface.

API reference
PropTypeDefaultDescription
valueReact.ComponentProps<typeof ProgressPrimitive.Root>['value']—Progress value passed to Radix Progress Root. The component uses this value to calculate the fill; retro mode rounds it to the nearest of 20 segments.
variant"default" | "retro"—Selects the fill style. "retro" renders 20 square segments; "default" and an omitted value use the continuous fill.
font"normal" | "retro"—Controls the retro class on the progress track. An omitted value also applies the retro class; "normal" disables it.
progressBgstring—Background class for filled portions. Defaults to "bg-primary"; in the continuous variant it is ignored when variant is "retro".
classNamestring—Class applied to the outer wrapper. A height class matching h-<number> or h-[...] is also extracted and applied to the progress track; otherwise the track defaults to h-2.
...propsReact.ComponentProps<typeof ProgressPrimitive.Root>—Other Radix Progress Root props, such as max, dir, getValueLabel, and ARIA attributes.
Accessibility
- Radix Progress Root provides progressbar semantics; provide an accessible name with aria-label or aria-labelledby.
- The value is passed to Radix, which exposes progress state to assistive technology. Use a meaningful max when the progress is not out of 100.
- The decorative border overlays are marked aria-hidden and do not add redundant information to the accessibility tree.
