## Where to use it

The little “?” next to a form field is where this one shines. In an insurance quote form, hover it beside “Excess amount” and a short explanation types itself out, as if someone were answering you. It is a typewriter tooltip made with HTML and CSS, and it also opens with keyboard focus.

The effect is meant for one short line. Past five or six words the typing feels slow and the tooltip gets too wide, so keep longer explanations for a help panel. If you change the text a lot, adjust the typing speed to match.

````text
I want to add the “Typewriter tooltip” block (Tooltips) from AIMRAN Library to my project.

## What it is
A question mark that answers back: the hint types itself out letter by letter when you hover it.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Quick tip"

## 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 = `

  position: relative;
  width: 3em;
  height: 3em;
  border-radius: 50%;
}

.uv-ttype span {
  position: absolute;
  z-index: 5;
  padding: .65em .85em;
  border-radius: .75em;

      <div
        style={{
