# [[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 checklist** — `dir="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
|
|
<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">
|
|
```
