# Lunar atlas tooltip
> The near side of the Moon with its seas and craters marked: each gets a ring at its real size and opens its card.
- Category: [Tooltips](https://library.aimran.es/components/tooltips)
- Built with: HTML + CSS
- Live editor: https://library.aimran.es/blocks/uv-tip-lunar-atlas
- Library: AIMRAN Library (https://library.aimran.es), free, no sign-up, by Aimran Oukham
## Where to use it
A Moon drawn entirely with layered CSS gradients: dark maria, bright craters, the faint rays of Tycho and a soft limb shadow on a starry card. Five features are buttons sized to their real extent on the disc. Hover or focus one and a dashed ring snaps around it while an atlas label gives its name, type, diameter and a short fact, like the Apollo 11 landing.
The main color sets the rings and the detail line, the second the night around the Moon. Add more craters by giving each one a position and a size in percent, or adapt the idea to a planet, an asteroid or a museum object.

I want to add the “Lunar atlas tooltip” block (Tooltips) from AIMRAN Library to my project.
## What it is
The near side of the Moon with its seas and craters marked: each gets a ring at its real size and opens its card.
## Chosen settings
- Main color: #fcd34d
- Secondary color: #0b0d14
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Cara visible de la Luna"
## 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.
