# Trail signpost 404 > A wooden trail signpost on a topographic map; the 404 board hangs from one nail and the compass cannot decide. - Category: [404](https://library.aimran.es/components/404) - Built with: HTML + CSS - Live editor: https://library.aimran.es/blocks/404-trail - Library: AIMRAN Library (https://library.aimran.es), free, no sign-up, by Aimran Oukham ## Where to use it Hiking clubs, outdoor brands and tourism sites can use this mountain error page. A wooden post with red and white trail marks holds arrow boards to a refuge, a viewpoint and the trailhead, while the board for page 404 hangs loose from a single nail and a compass needle spins around without finding north. The background draws contour lines with repeating gradients, so there are no images. Hovering a board makes it wobble, and reduced motion leaves the loose board still. Change the forest green accent and link the button to your start page. ## Code ### HTML ```html 404 · Page not found

Trail GR 404

This trail leads nowhere.

We've followed every trail mark and the page isn't on the map. Turn around and head back to the trailhead.

); } ``` ## 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 “Trail signpost 404” block (404) from AIMRAN Library to my project. ## What it is A wooden trail signpost on a topographic map; the 404 board hangs from one nail and the compass cannot decide. ## Chosen settings - Accent color: #2f6b3a - Speed: 1x (from 0.5 to 2x) - Title: "Este sendero no lleva a ninguna parte." - Message: "Hemos seguido todas las marcas y la página no aparece en el mapa. Da media vuelta y vuelve al inicio del camino." - Button: "Volver al inicio del camino" ## 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 import type { CSSProperties } from "react"; const css = ` .n4-trail { --accent: #2f6b3a;
