RTL (Right-to-Left) Learning Design
Also known as RTL · التصميم من اليمين إلى اليسار (RTL)
Definition
RTL design adapts a learning interface for right-to-left languages such as Arabic: mirroring layout and navigation, flipping directional icons and progress indicators, aligning text and tables to the right, and handling bidirectional text where Latin terms, numbers or code appear inside Arabic sentences.
Mirroring is not universal, and knowing the exceptions is the skill. Layout, navigation order and directional arrows flip; clocks, media playback controls, numerals and logos do not. Interfaces that mirror everything mechanically produce results that read as broken to Arabic speakers.
Bidirectional text is where most implementations fail. An English acronym or a version number inside an Arabic sentence can push punctuation and brackets to the wrong end unless the markup marks the boundary. The defects concentrate on small screens and in tables, so RTL verification belongs on a phone, in Arabic, as a release condition rather than a final check.
