# Car dashboard 404 > A car instrument cluster at night: the needles run their check, the odometer rolls to 404 and the engine light stays on. - Category: [404](https://library.aimran.es/components/404) - Built with: HTML + CSS - Live editor: https://library.aimran.es/blocks/404-garage - Library: AIMRAN Library (https://library.aimran.es), free, no sign-up, by Aimran Oukham ## Where to use it Garages, car dealers and motoring sites can use this instrument cluster as their error page. On load both needles sweep the full dial and come back, the mechanical odometer drums roll up to 000404, and the warning lights run their test until only the amber engine light is left on. The round start button replays the check and gives the rev counter a quick blip, while the idle needle trembles slightly. Gauges are drawn in inline SVG with real tick marks. Change the needle color with the accent and point the button home. ## Code ### HTML ```html 404 · Page not found

The warning light has been on for a while and the diagnostics only return code 404. Go back home while we take a look.

); } ``` ## 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 “Car dashboard 404” block (404) from AIMRAN Library to my project. ## What it is A car instrument cluster at night: the needles run their check, the odometer rolls to 404 and the engine light stays on. ## Chosen settings - Accent color: #ff5a1f - Speed: 1x (from 0.5 to 2x) - Title: "Revisa el motor: esta página no arranca." - Message: "El testigo de avería lleva un rato encendido y el diagnóstico solo devuelve el código 404. Vuelve al inicio mientras la revisamos." - 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, type CSSProperties } from "react";
