Stylis-plugin-rtl is a Stylis plugin that automatically transforms CSS rules to support right-to-left (RTL) layouts. By processing CSS, it flips properties like margin-left to margin-right and adjusts other directional styles for languages read from right to left. This plugin simplifies the creation of bidirectional stylesheets, reducing the need for manual RTL-specific CSS and ensuring a consistent user experience across different language directions. It seamlessly integrates with Stylis, enabling RTL transformations within existing CSS authoring workflows.
