## Where to use it

A driver’s view at dusk with a head-up display floating on the windshield. The road is an SVG drawn in perspective whose lane marks move with the speed, and the HUD glows in one color with a faint offset ghost, the double reflection you get from the two faces of laminated glass. Above the limit, the numbers turn amber.

Use the plus and minus buttons, or hold them, to change the speed. Recolor the projection and warning tones and type the next street in the text field. It suits car configurators, navigation apps and mobility landing pages.

## 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 “Windshield head-up display” block (Liquid Glass) from AIMRAN Library to my project.

## What it is
Speed, limit and next turn projected on the car glass, with the faint double image of a real windshield.

## Chosen settings
- Main color: #5eead4
- Secondary color: #ff9f43
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Calle Mayor"

## 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.
