# Take a number 404 > The deli counter ticket dispenser: the display moves on to 401, 402, 403 and skips your number, 404. - Category: [404](https://library.aimran.es/components/404) - Built with: HTML + CSS - Live editor: https://library.aimran.es/blocks/404-queue - Library: AIMRAN Library (https://library.aimran.es), free, no sign-up, by Aimran Oukham ## Where to use it Anyone who has queued at a market stall knows the red dispenser and the glowing number above the counter. In this error page the display counts 401, 402 and 403 and then jumps straight to 405, while your paper ticket keeps saying 404 and a note asks what happened to it. The take a number button tears off the ticket and a fresh one slides out of the slot, always with the same 404. The counter uses a ghosted LED look in plain CSS. Adjust the red accent to your brand. ## Code ### HTML ```html 404 · Page not found

); } ``` ## Prompt for AI assistants Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…): ````text I want to add the “Take a number 404” block (404) from AIMRAN Library to my project. ## What it is The deli counter ticket dispenser: the display moves on to 401, 402, 403 and skips your number, 404. ## Chosen settings - Accent color: #e63946 - Speed: 1x (from 0.5 to 2x) - Title: "Su turno ha pasado de largo." - Message: "El marcador se ha saltado la página 404 y nadie sabe por qué. Coja otro número o vuelva al inicio." - Button: "Volver al inicio" ## What I need 1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing. 2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file. 3. Expose the settings above as props (or CSS variables) with those values as defaults. 4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens. 5. Make it look right in light and dark mode. 6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support. 7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result. ## Reference code ```tsx // @ts-nocheck: setup() es JavaScript del DOM sin tipos. import { useEffect, useRef } from "react";
