## Where to use it

Some values only make sense in whole steps. A restaurant review site asking for a minimum of three stars, a hotel search by category, a gym app setting training days per week. The ticks show every possible stop and the handle snaps to each one, so nobody ends up at 3.7. Look for it as a stepped range slider.

Keep the number of steps low, five or six. With twenty ticks the marks blur into a line and the snapping stops being useful. Show the current value in large type next to the label, as in the demo.

````text
I want to add the “Stepped slider with tick marks” block (Filters) from AIMRAN Library to my project.

## What it is
A slider that snaps to whole steps, with the handle growing as you drag and passed ticks lighting up.

## 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.
