# [[W3CSS Badges]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
W3.CSS provides exactly ONE badge class (`w3-badge`, circular black by default) and achieves every visual variation — colored, sized, positioned inside buttons/lists/tables — purely through combination with OTHER existing classes (`w3-color`, `w3-size`, `w3-right`, `w3-margin-*`), rather than offering dozens of badge-specific variants. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **`w3-badge`** — the ONLY badge class; circular, black by default. [S1]
|
|
- **Color via composition** — `w3-badge w3-green`, `w3-badge w3-red`, etc. [S1]
|
|
- **Size inheritance** — a badge inherits its container's font size by default; `w3-size` classes override it. [S1]
|
|
- **Right-aligned list badges** — `w3-right` (float) + `w3-margin-right` positions a badge at the end of a list item. [S1]
|
|
- **UTF-8 Dingbat alternative** — single-digit circled numerals (❶❷❸...➉) via Unicode escapes as a badge-free alternative for simple counters. [S1]
|
|
|
|
## 📖 세부 내용 (Details)
|
|
- Basic badge: `<p>Updates <span class="w3-badge">9</span></p>`. [S1]
|
|
- Colored: `<p>News <span class="w3-badge w3-green">6</span></p>`. [S1]
|
|
- In a button: `<button class="w3-btn w3-black">Button <span class="w3-badge w3-margin-left w3-white">1</span></button>`. [S1]
|
|
- Right-aligned in a list: `<li>Jill <span class="w3-badge w3-right w3-margin-right">1</span></li>`. [S1]
|
|
- UTF-8 dingbat numerals: `❶ ❷ ❸` (❶ ❷ ❸) inside a `w3-xxlarge` div. [S1]
|

|
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
|
소스에서 모순되는 정보는 발견되지 않음.
|
|
|
|
## 🛠️ 적용 사례 (Applied in summary)
|
|
현재 발견된 실제 적용 사례가 없습니다 — 리스트 항목 끝에 우측 정렬된 배지를 붙이는 것이 카운터/알림 표시의 대표 실전 사례다. [S1]
|
|
|
|
## 💻 코드 패턴 (Code patterns)
|
|
Right-aligned badge in a list item (HTML):
|
|
```html
|
|
<ul class="w3-ul w3-border">
|
|
<li>Jill <span class="w3-badge w3-right w3-margin-right">1</span></li>
|
|
<li>Eve <span class="w3-badge w3-right w3-margin-right">2</span></li>
|
|
</ul>
|
|
```
|
|
