# Chat message that flies up

> The text leaves the input and turns into a bubble, then goes from sent to delivered and read before the other person replies.

## Where to use it

Sending a chat message feels better when you can see it travel. Here the text slides out of the input and settles as a bubble in the thread, the receipt changes from Sent to Delivered and Read with a second tick, and a typing indicator leads into a reply. It works with Enter or the round send button.

The main color paints your bubbles and the send button, the secondary one marks read receipts. The first message is the editable text, and the replies rotate through a short list in the script. Use it for support widgets, booking assistants or messaging mockups.

## 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 “Chat message that flies up” block (Microinteractions) from AIMRAN Library to my project.

## What it is
The text leaves the input and turns into a bubble, then goes from sent to delivered and read before the other person replies.

## Chosen settings
- Main color: #0d9488
- Secondary color: #38bdf8
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Perfecto, ¿a las ocho?"

## 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.
