Initially fork of storybook-addon-css-user-prefs to support sb@^8.0.0

List of supported modes:

• prefers-color-scheme
• prefers-contrast
• prefers-reduced-data
• prefers-reduced-motion
• prefers-reduced-transparency
• ~~print~~ (todo)
• ~~noscript~~ (todo)

Installation

1. Package installation pnpm add -D storybook-addon-render-modes

2. Addon registration

const config: StorybookConfig = {
  // ...yourOtherSettings
  addons: [
    'storybook-addon-render-modes',
  ],
};

export default config;

Caveats

This addon doesnt force changing of rendering mode in browser level (seems impossible). But instead it uses hacky approach: we go through document.styleSheets via JS and manually rewriting media style rules.

This approach may work not as expected in some cases. Feel fre to create an issue for such cases.
