Introduction to commonrtl.css

This CSS resource package provides native right-to-left (RTL) layout support for Cisco collaboration web interfaces, including Unified Communications Manager (CUCM) 14.0(1) and Webex Control Hub. Designed for Middle Eastern deployments, it enables:

  • Automatic mirroring of UI elements
  • Arabic/Urdu text alignment compliance
  • Bidirectional (BiDi) content rendering

As part of Cisco’s Globalization Toolkit 2025, this package integrates with Cisco Expressway Series and UCS C-Series servers hosting web administration portals. The 14.0(1) release aligns with W3C Internationalization Best Practices and supports Chrome 115+ & Safari 18+ browsers.

Key Features and Enhancements

  1. ​​Logical Property Implementation​​

    • Replaces physical properties (margin-left/right) with logical equivalents (margin-inline-start)
    • 60% reduction in manual CSS overrides for Arabic locales

  2. ​​Flexbox & Grid Optimization​​

    • Automatic flex-direction reversal in RTL contexts
    • Native support for mirrored grid-template-columns

  3. ​​Iconography Handling​​

    • Auto-flips directional icons (arrows, carousels) via transform: scaleX(-1)
    • Preserves non-directional icons (brand logos, status indicators)

  4. ​​Performance Improvements​​

    • 30% faster layout rendering through CSS variable substitution
    • Tree-shaking removes unused RTL rules during build processes

  5. ​​Security Validation​​

    • SHA-384 hashing ensures file integrity
    • Cisco Trust Verification Module (TVM) compatibility
