## Where to use it
A grid of hexagons blinking on and off has a techy, sci-fi feel, perfect behind the hero of a cybersecurity company, the landing page of a hackathon or the main menu of a strategy game. The cells light up randomly in your colors, and the edges fade into the background so the center stays clean for your content.
Raise the scale for bigger, calmer cells behind long headlines, or lower it for a denser texture. Slower speeds keep it from competing with the text. If you want a matching loader, the hexagon ring in this library shares the look.

I want to add the “Honeycomb background” block (Backgrounds) from AIMRAN Library to my project.
## What it is
A full-screen honeycomb where hexagons light up at random, like a living grid, in pure HTML and CSS.
## Chosen settings
- Color 1: #0071e3
- Color 2: #8b5cf6
- Color 3: #14b8a6
- Speed: 1x (from 0.2 to 3x)
- Density / scale: 1x (from 0.5 to 2x)
- Opacity: 1 (from 0.2 to 1)
## 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.
