# E-ink reader page

> A novel page on an e-ink screen: turning the page triggers the typical negative flash and moves the progress bar.

## Where to use it

E-readers have a recognizable quirk: the screen flashes to negative for a moment when the page changes. This card copies it with a stepped invert filter on a paper-grey screen, serif justified text and a thin progress line. Tap the left or right side, or use the arrow keys. It fits book apps, publishers, reading trackers and newsletter previews.

The main color is the ink and the second the screen tone. Put your own paragraphs in the pages list and adjust the page numbers, and keep each page short enough to fit the screen.

## Prompt for AI assistants

Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):

````text
I want to add the “E-ink reader page” block (Cards) from AIMRAN Library to my project.

## What it is
A novel page on an e-ink screen: turning the page triggers the typical negative flash and moves the progress bar.

## Chosen settings
- Main color: #262521
- Secondary color: #e8e6dd
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "La sombra del faro"

## 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.
