## Where to use it

Tag inputs fit anywhere people add several short items at once: skills on a job profile, keywords for a blog post, ingredients to exclude on a recipe site or labels in a task manager. Each tag pops in as a coloured chip and shrinks away when removed. A tags input in HTML, CSS and a bit of JavaScript.

In this version only Enter creates a tag, not commas, so mention it in the placeholder as the demo does. If there is a fixed list of options behind the scenes, suggestions will serve people better than free typing.

## 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 “Tag input” block (Inputs) from AIMRAN Library to my project.

## What it is
Press Enter to turn a word into a tag; click its × or hit backspace to remove it with a small shrink.

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

## 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.
