W3CSS RTL

🎯 한 줄 통찰 (One-line insight)

Full RTL support requires FOUR coordinated changes, not just one CSS class — dir="rtl" on <html> for semantic correctness, w3-rtl on <body> for component behavior, swapping margin-left for margin-right on main content, and repositioning the sidebar with right:0 instead of left:0 — meaning w3-rtl alone is necessary but not sufficient for a properly mirrored layout. [S1]

🧠 핵심 개념 (Core concepts)

  • w3-rtl (W3.CSS 5+) — adjusts text direction/alignment for right-to-left languages (Arabic, Hebrew, Persian). [S1]
  • Scoped application — can be applied globally to <body> or locally to a specific <div>. [S1]
  • w3-ltr — reverts a specific section back to left-to-right within an otherwise RTL page. [S1]
  • Full RTL checklistdir="rtl" on <html> (semantic correctness), w3-rtl on <body> (component behavior), margin-right instead of margin-left for main content, sidebar positioned with right:0. [S1]
  • Manual adjustment still needed — other text alignment, margins, paddings, and floats must be checked to ensure layout components flip appropriately. [S1]

📖 세부 내용 (Details)

  • Global RTL: <body class="w3-container w3-rtl"><h2>مرحبا بك في موقعي</h2></body>. [S1]
  • Scoped RTL: <div class="w3-container w3-rtl"><h2>...</h2></div>. [S1]
  • Reverting a section: <div class="w3-ltr"><p>This section is back to left-to-right.</p></div>. [S1]
  • Full RTL page setup: <html lang="ar" dir="rtl"><body class="w3-rtl"><main class="w3-container" style="margin-right:200px"><nav class="w3-sidebar" style="width:200px; right:0">. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • w3-rtl 단독으로는 불충분: 완전한 RTL 레이아웃을 위해서는 dir="rtl" 속성, margin-right 사용, 사이드바 위치 조정까지 함께 필요하다는 점이 체크리스트로 명시됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 아랍어 사이트를 위한 전체 페이지 RTL 설정(html+body+main+sidebar)이 실전 국제화의 대표 사례다. [S1]

💻 코드 패턴 (Code patterns)

Full RTL page structure with sidebar repositioning (HTML):

<html lang="ar" dir="rtl">
<body class="w3-rtl">
  <main class="w3-container" style="margin-right:200px">
  <nav class="w3-sidebar" style="width:200px; right:0">
