# [[W3CSS Buttons]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
W3.CSS's philosophy is that ANY element can be a button, not just `<button>` — the tutorial explicitly shows `<input type="button">` and `<a>` tags gaining identical button behavior from the same `w3-button`/`w3-btn` classes, and even states "Any div, header, footer or other containers can be a w3-button" with a live image demonstrating a picture styled as a clickable button. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **`w3-btn`** — rectangular button with a SHADOW hover effect; default color black. [S1]
|
|
- **`w3-button`** — rectangular button with a GRAY hover effect; default color inherits from parent (v4+). [S1]
|
|
- **`w3-bar`** — horizontal container for grouping buttons (navigation menus). [S1]
|
|
- **`w3-bar-item`** — removes the gap between grouped buttons inside a `w3-bar`. [S1]
|
|
- **`w3-block`** — full-width (100%) button. [S1]
|
|
- **`w3-circle`** — circular button. [S1]
|
|
- **`w3-ripple`** — click-triggered ripple animation effect. [S1]
|
|
- **`w3-disabled`** — CSS-only disabled appearance (opaque, "no parking sign" cursor) for elements that don't support the native `disabled` attribute (like `<a>`). [S1]
|
|
- **`w3-show-inline-block`** — lets multiple `w3-bar` groups sit on the same line. [S1]
|
|
|
|
## 📖 세부 내용 (Details)
|
|
- Any element as a button: `<input class="w3-button w3-black" type="button" value="Input Button"> <button class="w3-button w3-black">Button Button</button> <a href="..." class="w3-button w3-black">Link Button</a>`. [S1]
|
|
- Grouped, gapless bar buttons: `<div class="w3-bar"><button class="w3-bar-item w3-button w3-black">Button</button>...</div>`. [S1]
|
|
- Full-width with custom width via inline style: `<button class="w3-button w3-block w3-black" style="width:30%">Button</button>`. [S1]
|
|
- Disabled link (since `<a>` has no native `disabled` attribute): `<a class="w3-button w3-disabled" href="...">Link Button</a>`. [S1]
|
|
|
|
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
|
- **모든 요소가 버튼이 될 수 있음**: div, header, footer, 심지어 이미지까지도 w3-button/w3-btn 클래스로 버튼처럼 동작할 수 있다는 점이 명시적으로 시연됨. [S1]
|
|
|
|
## 🛠️ 적용 사례 (Applied in summary)
|
|
현재 발견된 실제 적용 사례가 없습니다 — w3-bar-item으로 간격 없이 버튼을 묶어 내비게이션 바를 만드는 것이 실전 UI 구성의 대표 사례다. [S1]
|
|
|
|
## 💻 코드 패턴 (Code patterns)
|
|
Gapless button bar acting as a navigation menu (HTML):
|
|
```html
|
|
<div class="w3-bar w3-black">
|
|
<button class="w3-bar-item w3-button">Button</button>
|
|
<button class="w3-bar-item w3-button">Button</button>
|
|
<button class="w3-bar-item w3-button">Button</button>
|
|
</div>
|
|
```
