## Where to use it

Neon belongs on dark interfaces with a bit of attitude: the graphics options of a game launcher, a “Turbo mode” switch in a crypto dashboard or the filters of a music festival site. The glow makes the active options visible from across the room. A neon checkbox in CSS that uses your accent colour for the light.

On a white background the glow almost disappears, so save it for dark themes. Bright, saturated colours such as cyan, magenta or lime give the most convincing neon; pastel shades look washed out.

````text
I want to add the “Neon checkbox” block (Checkboxes) from AIMRAN Library to my project.

## What it is
An outlined box that lights up with a neon glow and a shining tick when switched on.

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

## 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.
