OverType is a lightweight, zero-dependency Markdown editor that uses a transparent HTML textarea layered over a rendered markdown preview. This approach allows users to type in a standard textarea while seeing formatted output simultaneously.

Who is OverType designed for?

OverType is designed for developers or projects that require a simple, fast, and highly customizable Markdown editing solution without external dependencies, build steps, or complex frameworks. It targets those who prefer native browser features and minimal overhead.

How does OverType differ from other Markdown editors?

Unlike most WYSIWYG Markdown editors that rely on virtual DOM or ContentEditable, OverType uses a unique "transparent textarea over preview div" abstraction. This design eliminates common issues like ContentEditable bugs and reduces the total footprint to 91KB.

When should I consider using OverType?

You should consider OverType when integrating a basic Markdown editor into a web application where performance, small bundle size, and avoiding complex dependencies are critical. It's ideal for scenarios needing a simple script-tag integration without npm or build processes.

How does OverType maintain native textarea functionality?

OverType keeps native textarea functionality because it literally uses a standard HTML textarea element. It simply makes the textarea's background and text color transparent, sets caretColor to black, and then positions it precisely over a preview div, syncing input and scroll events.
