## Where to use it

This is the bottom bar you see in plenty of shopping and delivery apps: Home, Search, Favourites, Profile. Showing the label only on the active tab keeps the bar compact while still telling people where they are. It suits a mobile web shop or a PWA. You'll also find it described as an animated bottom navigation bar.

Pick icons people recognise without a label, because three of the four will be shown bare. A house, a magnifier and a heart are safe bets. Four items fit comfortably; five starts to crowd a small phone.

````text
I want to add the “Icon tabs with expanding label” block (Filters) from AIMRAN Library to my project.

## What it is
Only the active tab shows its label; the others stay as icons, which saves space on small screens.

## 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.
