## Where to use it

When something fails, a small shake says “this needs you” without a scary red page. Picture a food delivery app where the order cannot reach the restaurant, or a checkout that loses connection at the last step: the error toast explains what happened and puts “Retry” one tap away, so nobody has to fill everything in again.

Say what went wrong and what to do next in plain words; “Error 500” helps nobody. Keep the shake for real errors, not warnings. And if the problem is on your side, say so: people forgive a failed payment much faster that way.

## Code

### HTML

```html
<div class="uv-ze"><button class="fire">Trigger error</button><div class="toast"><i>!</i><span><b>Couldn’t connect</b><small>Check your connection.</small></span><button class="retry">Retry</button></div></div>
```

## 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 “Shake error toast” block (Toasts) from AIMRAN Library to my project.

## What it is
An error message that slides in with a short shake and offers a “Retry” button right where you need it.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Couldn’t connect"

## 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.
