# [[W3CSS Intro]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
This "Kitchen Sink" intro page is deliberately a survey, not a tutorial — it flashes a tiny live sample of EVERY major W3.CSS feature (colors, containers, panels, cards, grid, flexbox, modals, tabs, animations, etc.) in one scroll, functioning as a visual table of contents that previews what each later chapter will teach in depth. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **Purpose** — a single-page "kitchen sink" demo giving a bite-sized preview of nearly every W3.CSS component before diving into individual chapters. [S1]
|
|
- **Core class families previewed** — `w3-container`, `w3-panel`, `w3-card`, `w3-table`, `w3-ul`, `w3-button`/`w3-btn`, `w3-tag`/`w3-badge`, `w3-grid`, `w3-flex`, `w3-row`, `w3-display-*`, `w3-modal`, `w3-dropdown`, `w3-bar` (navigation), `w3-animate-*`. [S1]
|
|
- **w3-grid vs w3-flex distinction (previewed here, detailed later)** — grid is two-dimensional (rows AND columns); flex is one-dimensional (rows OR columns). [S1]
|
|
|
|
## 📖 세부 내용 (Details)
|
|
- Container example: `<div class="w3-container w3-teal"><h1>This is a Header</h1></div>`. [S1]
|
|
- Panel example: `<div class="w3-panel w3-red"><p>I am a panel</p></div>`. [S1]
|
|
- Card example: `<div class="w3-card-4"><img src="img_snowtops.jpg" alt="Alps"><div class="w3-container w3-center"><p>French Alps</p></div></div>`. [S1]
|
|
- Grid example: `<div class="w3-grid"><div>1</div><div>2</div><div>3</div><div>4</div></div>`. [S1]
|
|
- Flex example: `<div class="w3-flex" style="gap:8px"><div>1</div><div>2</div><div>3</div></div>`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
|
소스에서 모순되는 정보는 발견되지 않음.
|
|
|
|
## 🛠️ 적용 사례 (Applied in summary)
|
|
현재 발견된 실제 적용 사례가 없습니다 — 이 페이지 자체가 W3.CSS 전체 기능의 축소판 시연이며, 각 컴포넌트는 이후 챕터에서 상세히 다뤄진다. [S1]
|
|
|
|
## 💻 코드 패턴 (Code patterns)
|
|
Grid vs flex, previewed side by side (HTML):
|
|
```html
|
|
<div class="w3-grid"> <!-- two-dimensional: rows AND columns -->
|
|
<div>1</div><div>2</div><div>3</div><div>4</div>
|
|
</div>
|
|
<div class="w3-flex" style="gap:8px"> <!-- one-dimensional: rows OR columns -->
|
|
<div>1</div><div>2</div><div>3</div>
|
|
</div>
|
|
```
