# [[W3CSS Round]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
`w3-round` and `w3-round-medium` are silent aliases — both apply the exact same 4px border-radius — following the same "plain name = medium tier" pattern already seen in `w3-card`/`w3-card-2`, meaning W3.CSS consistently treats the unqualified class name as shorthand for its own "medium" size variant across multiple class families. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **Five rounding tiers** — `w3-round-small` (2px), `w3-round`/`w3-round-medium` (4px, aliases), `w3-round-large` (8px), `w3-round-xlarge` (16px), `w3-round-xxlarge` (32px). [S1]
|
|
- **`w3-circle`** — renders content inside a perfect circle; works on both images and text containers. [S1]
|
|
- **Nested circles** — a circle can contain another circle (e.g. a smaller red circle centered inside a larger green one) by stacking `w3-circle` on nested elements with different padding/sizing. [S1]
|
|
|
|
## 📖 세부 내용 (Details)
|
|
- Basic rounding: `<div class="w3-round w3-teal">w3-round</div>`. [S1]
|
|
- Circular image: `<img class="w3-circle" src="img_car.jpg" alt="Car">`. [S1]
|
|
- Text inside a circle: `<div class="w3-padding-32 w3-red w3-circle w3-center"><h1>The w3-circle Class</h1></div>`. [S1]
|
|
- Nested circle-in-circle: `<div class="w3-padding-32 w3-green w3-circle"><div class="w3-padding-32 w3-red w3-circle w3-center" style="width:55%"><p class="w3-xlarge">Hello<br>W3.CSS!</p></div></div>`. [S1]
|
|
|
|
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
|
- **plain 이름 = medium 별칭 패턴**: w3-round와 w3-round-medium이 완전히 동일한 4px 값을 가진다는 점이 카드 클래스(w3-card=w3-card-2)와 동일한 명명 관습임을 보여준다. [S1]
|
|
|
|
## 🛠️ 적용 사례 (Applied in summary)
|
|
현재 발견된 실제 적용 사례가 없습니다 — 원 안에 원을 중첩시켜 텍스트를 배치하는 것이 시각적 강조 디자인의 대표 사례다. [S1]
|
|
|
|
## 💻 코드 패턴 (Code patterns)
|
|
Nested circles with centered text (HTML):
|
|
```html
|
|
<div class="w3-padding-32 w3-green w3-circle">
|
|
<div class="w3-padding-32 w3-red w3-circle w3-center" style="width:55%">
|
|
<p class="w3-xlarge">Hello<br>W3.CSS!</p>
|
|
</div>
|
|
</div>
|
|
```
|
|
