Carta
Modern, lightweight, powerful Markdown Editor.
# Introduction
> [!NOTE]
> Carta has recently been updated to `v4`, which features numerous major changes.
>
> Follow the [Migration Guide](http://beartocode.github.io/carta/migration) to update your project.
Carta is a **lightweight**, **fast** and **extensible** Svelte Markdown editor and viewer. It is powered by [unified](https://github.com/unifiedjs/unified), [remark](https://github.com/remarkjs/remark) and [rehype](https://github.com/rehypejs/rehype). Check out the [examples](http://beartocode.github.io/carta/examples) to see it in action.
Differently from most editors, Carta does not include a code editor, but it is _just_ a textarea with syntax highlighting, shortcuts and more.
This is a fork of carta which applies the following changes:
- Replace Shiki syntax higlighter with Prism.js (much more lightweight, 90kB vs 385kB bundle size for minimal test application)
- Make markdown renderer class configurable and set it to `prose` by default (for Tailwind support)
- Make markdown input usable without JS
