## Where to use it
Divider tabs from a ring binder: pastel card tabs stick out of a ruled notebook page with punched holes and a red margin line. The chosen tab slides forward and the page turns slightly as the new list appears in a handwritten style. It is pure CSS with a tab script, made for note apps, planners, recipe sites and personal dashboards.
Give each tab its own colour in the data and use the main color for the ink. Short, single words work best on the vertical labels, and three to five tabs keep the edge tidy.

I want to add the “Ring binder divider tabs” block (Navigation) from AIMRAN Library to my project.
## What it is
Coloured card tabs stick out from the edge of a ruled notebook, and the page turns when you pick another one.
## Chosen settings
- Main color: #1e3a8a
- Secondary color: #fffdf5
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Cuaderno"
## 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.
