# Blueprint callout tooltip
> A blue technical drawing of a lamp: each hotspot draws a leader line to a card with material and measurements.
- Category: [Tooltips](https://library.aimran.es/components/tooltips)
- Built with: HTML + CSS
- Live editor: https://library.aimran.es/blocks/uv-tip-blueprint-callout
- Library: AIMRAN Library (https://library.aimran.es), free, no sign-up, by Aimran Oukham
## Where to use it
A desk lamp drawn as white SVG lines on a blueprint grid, with a dimension line and a title block. Hover or focus one of the dashed hotspots and a yellow leader line draws itself from the part to a callout with its name, material and measurement in a monospaced font. The reveal uses :has() and stroke-dashoffset, with no JavaScript beyond the opening demo.
The main color is the paper blue and the second the pencil yellow of the leaders. Redraw the object in the SVG, then adjust the leader paths and the callout positions in percentages for furniture, machines or product anatomy pages.
## Code
### HTML
```html
160 Head 0.8 mm aluminum Ø 140 mm Joint 12 N spring Turns 0 to 90° Base Cast iron Ø 160 mm · 1.2 kg Lamp L-2 SCALE 1:5 (null);
useEffect(() => {
const el = ref.current?.firstElementChild;
return el ? setup(el) : undefined;
}, []);
return (
<>
160 Head 0.8 mm aluminum Ø 140 mm Joint 12 N spring Turns 0 to 90° Base Cast iron Ø 160 mm · 1.2 kg Lamp L-2 SCALE 1:5
);
}
```

I want to add the “Blueprint callout tooltip” block (Tooltips) from AIMRAN Library to my project.
## What it is
A blue technical drawing of a lamp: each hotspot draws a leader line to a card with material and measurements.
## Chosen settings
- Main color: #0a4b8c
- Secondary color: #ffd166
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Lámpara L-2"
## 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.
