8-bit Textarea
An 8-bit styled wrapper around the standard shadcn/ui Textarea. It adds a square-cornered frame and uses retro pixel lettering by default, with an option to use normal font styling.

- applied the registry's theme (tokens, fonts and CSS from the registry preview settings)
Installation
pnpm dlx shadcn@latest add @8bitcn/textarea
Requires @8bitcn in the registries of your components.json (shadcn adds official directory namespaces automatically).
Usage
usage.tsx
import { Textarea } from "@/components/ui/8bit/textarea";export function MessageFields() { return ( <div className="space-y-4"> <Textarea aria-label="Message" placeholder="Write a message..." /> <Textarea font="normal" aria-label="Notes" placeholder="Add notes..." /> <Textarea aria-label="Feedback" rows={5} defaultValue="Thanks for playing!" /> </div> );}- Use for multi-line input in interfaces with a retro, pixel-art, or arcade-inspired visual style.
- Use when the textarea should match other 8-bit styled controls while retaining standard textarea behavior.
- Set font="normal" when you want the framed 8-bit appearance without the retro typeface.

PropTypeDefaultDescription
font"normal" | "retro" | null—Controls the font styling. "normal" omits the retro class; "retro" applies it. When omitted, the component applies the retro class.
asChildboolean—Declared as an optional prop and forwarded to the underlying shadcn/ui Textarea. This component does not implement Slot-based rendering.
TextareaHTMLAttributes<HTMLTextAreaElement>React.TextareaHTMLAttributes<HTMLTextAreaElement>—Accepts standard textarea attributes and event handlers, including placeholder, rows, value, defaultValue, and onChange. className is applied to both the outer wrapper and the underlying textarea.
Accessibility
- The underlying control is a native textarea and accepts standard accessibility attributes such as aria-label, aria-describedby, and required.
- Provide an accessible name, typically with a visible associated label or an aria-label.
- The decorative border overlays have aria-hidden="true" and pointer-events-none, so they do not add accessible content or intercept pointer input.
