# Origami paper folding loader

> A sheet of origami paper folds its four corners to the center one by one, shows its plain back and opens again.

## Where to use it

A patterned origami sheet seen in perspective folds each corner along its diagonal with real 3D rotations, and the face switches to the plain cream back when the flap is edge on. After the fourth fold it unfolds in reverse order. It suits stationery shops, Japanese restaurants, design studios and calm craft brands.

The main color is the printed side of the paper and the second the dot pattern. Choose a strong paper color and leave plenty of space around it, since the sheet tilts and casts a soft shadow.

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 “Origami paper folding loader” block (Loaders) from AIMRAN Library to my project.

## What it is
A sheet of origami paper folds its four corners to the center one by one, shows its plain back and opens again.

## Chosen settings
- Main color: #d62839
- Secondary color: #f7c873
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)

## 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.
