# [[W3CSS Text]]

## 🎯 한 줄 통찰 (One-line insight)
`w3-opacity` is explicitly "designed to work with all colors" as a class, while `text-shadow` requires inline `style` attributes and doesn't have a dedicated W3.CSS class — meaning opacity effects are first-class framework citizens while shadow effects lean on raw CSS3, a distinction with a practical consequence: text-shadow doesn't work in IE9 and earlier, but nothing in the source suggests w3-opacity shares that limitation. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`w3-left-align` / `w3-right-align`** — text alignment classes. [S1]
- **`w3-center`** — centers block-level content (not just text). [S1]
- **`w3-wide`** — applies wider letter-spacing. [S1]
- **`w3-opacity`** — reduces text opacity, works with any color. [S1]
- **Text shadow — CSS3, not a W3.CSS class** — applied via inline `style="text-shadow:1px 1px 0 #444"`; NOT supported in IE9 and earlier. [S1]
- **Composability** — opacity, shadow, bold, and color classes can all stack on one element simultaneously. [S1]

## 📖 세부 내용 (Details)
- Alignment: `<div class="w3-left-align"><p>Left aligned text.</p></div>` / `<div class="w3-right-align">...</div>`. [S1]
- Centering: `<div class="w3-container w3-center"><h2>Centered Content</h2><img ...><p>Some centered text.</p></div>`. [S1]
- Opacity: `<h2 class="w3-opacity">Text Opacity</h2>`. [S1]
- Shadow (inline style, no dedicated class): `<h2 class="w3-blue" style="text-shadow:1px 1px 0 #444">Text Shadow</h2>`. [S1]
- Stacked effects: `<h1 class="w3-text-yellow" style="text-shadow:1px 1px 0 #444"><b>Yellow Text + Shadow + Bold</b></h1>`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **text-shadow의 브라우저 제약**: IE9 이하에서는 text-shadow가 동작하지 않는다는 점이 명시적으로 경고됨. [S1]

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 투명도+그림자+굵게를 조합한 특수 텍스트 효과가 실전 활용의 대표 사례다. [S1]

## 💻 코드 패턴 (Code patterns)
Combining opacity, color, shadow, and bold on one heading (HTML):
```html
<div class="w3-panel w3-blue">
  <h1 class="w3-text-orange" style="text-shadow:1px 1px 0 #444">
    <b>Orange Text + Shadow + Bold</b>
  </h1>
</div>
```
