8-bit Popover
An 8-bit-styled wrapper around the standard shadcn/Radix Popover components. It adds a square, pixel-inspired border and retro typography to the popover content while keeping the trigger, anchor, and content APIs based on Radix.

PropTypeDefaultDescription
font"normal" | "retro" | null—Typography variant for the content. Set to "normal" to omit the retro class; any other value, including an omitted value, applies the retro class. The declared CVA default is "retro".
childrenReact.ComponentProps<typeof PopoverPrimitive.Content>["children"]—Content rendered inside the popover.
classNameReact.ComponentProps<typeof PopoverPrimitive.Content>["className"]—Additional class name merged with the wrapper's visual classes.
Radix Popover.Content propsReact.ComponentProps<typeof PopoverPrimitive.Content>—All other Radix Popover.Content props are accepted, including positioning props such as side, align, sideOffset, and alignOffset, as well as event handlers and accessibility attributes.
Accessibility
- Use a clearly named trigger so its purpose is understandable to screen-reader and keyboard users.
- The trigger and content are Radix Popover components, so their built-in keyboard and focus behavior is retained; test focus entry and return for your interaction.
- Use semantic controls and labels inside the content, and ensure the content remains usable when navigating by keyboard.
- The decorative border overlay is marked aria-hidden and does not add redundant content to the accessibility tree.
