# [[W3CSS Icons]]

## 🎯 한 줄 통찰 (One-line insight)
W3.CSS has NO icon system of its own — it's explicitly framework-agnostic here, supporting Font Awesome, Google Material Icons, and Bootstrap Icons interchangeably, each via a completely different markup convention (`<i class="fa fa-home">` vs. `<i class="material-icons">home</i>` vs. `<i class="glyphicon glyphicon-home">`), meaning the icon syntax you use depends entirely on which external CDN you chose to link, not on W3.CSS. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Two-step integration** — (1) link the icon library's CSS from a CDN in `<head>`, (2) add the icon's class name to an inline element (`<i>` or `<span>` are conventional). [S1]
- **Font Awesome syntax** — class-name-based: `<i class="fa fa-home"></i>`. [S1]
- **Material Icons syntax** — TEXT-content-based: `<i class="material-icons">home</i>` (the icon name is the element's text, not a class suffix). [S1]
- **Bootstrap Icons (glyphicons) syntax** — class-name-based like Font Awesome: `<i class="glyphicon glyphicon-home"></i>`. [S1]
- **Sizing via `w3-size` classes** — the same `w3-tiny` through `w3-jumbo` classes used elsewhere apply directly to icons too. [S1]

## 📖 세부 내용 (Details)
- Font Awesome setup: `<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"> <i class="fa fa-home"></i>`. [S1]
- Material Icons setup (note: icon name as TEXT, not class): `<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons"> <i class="material-icons">home</i>`. [S1]
- Bootstrap Icons setup: `<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"> <i class="glyphicon glyphicon-home"></i>`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **아이콘 라이브러리별 문법 차이**: Font Awesome/Bootstrap은 클래스명으로, Material Icons는 요소의 텍스트 내용으로 아이콘을 지정한다는 점이 세 예제의 직접 비교로 명확히 드러남. [S1]

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 세 아이콘 라이브러리 중 하나를 선택해 홈/검색/삭제 아이콘을 표시하는 것이 실전 UI 아이콘 사용의 표준 패턴이다. [S1]

## 💻 코드 패턴 (Code patterns)
Material Icons uses text content, not a class suffix, unlike Font Awesome (HTML):
```html
<!-- Font Awesome: icon name is part of the class -->
<i class="fa fa-home"></i>
<!-- Material Icons: icon name is the element's text content -->
<i class="material-icons">home</i>
```
