# Blueprint element inspector

> An inspect mode that covers the page with a blueprint grid and marks margin, padding and size of whatever you point at.

## Where to use it

Browser devtools draw boxes over elements, and this overlay turns that into a design piece. Switching it on lays a blueprint grid and rulers over the page, and pointing at an element slides orange hatched margins, green padding and a blue content box to it, plus a tag with its name and size. The rulers highlight its extent. It fits design system docs, tutorials and developer portfolios.

The main color is the blueprint and the second one the margins. Add data-ins to any element you want to inspect, move through them with the arrow keys and leave the mode with Escape or the same button.

I want to add the “Blueprint element inspector” block (Overlays) from AIMRAN Library to my project.

## What it is
An inspect mode that covers the page with a blueprint grid and marks margin, padding and size of whatever you point at.

## Chosen settings
- Main color: #2563eb
- Secondary color: #f97316
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Inspeccionar"

## 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.
