# Virtual waiting room queue

> A ticket queue with your place shown in rolling digits, a line of people moving forward and the notice when it is your turn.

## Where to use it

Big ticket sales put buyers in a queue, and this overlay makes the wait readable. Your position rolls down in large digits, a row of dots walks toward the door, the estimated time updates and a switch offers to notify you. It fits concerts, launches, sales and booking peaks.

The main color paints the page, your dot and the buttons, the second one the success badge. Connect the counter to your real queue position instead of the timer, and keep the leave button so people can step out with Escape too.

## 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 “Virtual waiting room queue” block (Overlays) from AIMRAN Library to my project.

## What it is
A ticket queue with your place shown in rolling digits, a line of people moving forward and the notice when it is your turn.

## Chosen settings
- Main color: #7c3aed
- Secondary color: #22c55e
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Estás en la cola"

## 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.
