# [[W3CSS Grid]]

## 🎯 한 줄 통찰 (One-line insight)
`w3-grid` is a thin wrapper (essentially just `display: grid`) that hands full control to STANDARD CSS Grid properties applied via inline `style` — `grid-template-columns`, `grid-column-start`, `gap`, etc. — meaning learning W3.CSS grid is really learning native CSS Grid, not a proprietary abstraction layer. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`w3-grid`** (W3.CSS 5.0+) — creates a two-dimensional grid container; children automatically become grid items. [S1]
- **`w3-grid-padding`** — the padded variant. [S1]
- **`grid-template-columns`** — sets column count/widths; accepts `auto`, `fr` (fractional), `px`, `%`, or `repeat()`. [S1]
- **`repeat(auto-fit, minmax(150px, 1fr))`** — a common responsive pattern letting columns auto-adjust to available width. [S1]
- **Item placement properties** — `grid-column-start`/`-end`, `grid-row-start`/`-end`, and their shorthands `grid-column`/`grid-row` (e.g. `grid-column:1/span 2` spans an item across 2 columns). [S1]
- **`grid-template-areas`** — names regions of the grid for semantic placement via `grid-area`. [S1]
- **Alignment** — `justify-content` (horizontal), `align-content` (vertical) — same value vocabulary as flexbox (`center`, `space-between`, `space-evenly`, etc.). [S1]

## 📖 세부 내용 (Details)
- Responsive auto-fit columns: `<div class="w3-grid" style="grid-template-columns:repeat(auto-fit,minmax(150px,1fr))">`. [S1]
- Spanning an item across columns: `<div style="grid-column:1/span 2">1</div>` inside a `w3-grid` container. [S1]
- Named grid areas: `<div class="w3-grid" style="grid-template-areas:'myArea myArea . .'"> <div style="grid-area:myArea">1</div> ...</div>`. [S1]
- Gap control: `<div class="w3-grid" style="gap:2px">`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **w3-grid vs w3-flex의 차원 차이**: grid는 행+열 2차원, flex는 행 또는 열 1차원 레이아웃이라는 점이 명시적으로 대비됨. [S1]

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — repeat(auto-fit, minmax()) 패턴이 반응형 카드 그리드 구성의 표준 실전 기법이다. [S1]

## 💻 코드 패턴 (Code patterns)
Responsive auto-fitting grid columns (HTML/CSS):
```html
<div class="w3-grid" style="grid-template-columns:repeat(auto-fit,minmax(150px,1fr))">
  <div>1</div><div>2</div><div>3</div><div>4</div>
</div>
```
