## What it is
RTLCSS is a Node.js framework and PostCSS plugin that automatically converts Left-To-Right (LTR) CSS stylesheets into their Right-To-Left (RTL) counterparts. It supports direction-sensitive CSS3 properties, control and value directives, string maps, and a CLI, so developers can author one LTR stylesheet and generate the mirrored RTL version.

## Use cases
- convert css from ltr to rtl for arabic websites
- generate right-to-left stylesheet automatically
- flip css properties like padding and margins for rtl languages
- mirror a bootstrap theme for rtl support
- postcss plugin to transform css direction
- build rtl version of css without maintaining two files
- handle direction-sensitive css3 properties like box-shadow and transforms

## When to choose
- you need to support RTL languages such as Arabic or Hebrew without hand-maintaining a second stylesheet
- you want a build-time or CLI tool that mirrors existing LTR CSS automatically
- you need fine-grained control over conversion via in-CSS directives and string maps

## When to avoid
- your site is LTR-only and will never need RTL support
- you prefer writing RTL styles manually or using a CSS logical-properties-first approach
- you need runtime direction switching rather than build-time stylesheet generation
