# [[HOWTO CSS Center Button]]

## 🎯 한 줄 통찰 (One-line insight)
This recipe is the EXACT SAME three techniques as `[[HOWTO CSS Center Vertical]]` (absolute+translateY, absolute+translate both axes, flexbox), just applied to a `<button>` element instead of generic text — confirming that these centering methods are element-agnostic: they operate purely on the CONTAINER's positioning/layout, completely indifferent to what kind of child element (text, button, image, or anything else) is being centered. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Element-agnostic centering** — the same `position: absolute` + `transform` or `display: flex` techniques from the general vertical-centering recipe apply unchanged to a button. [S1]
- **Vertical-only**: `.vertical-center { position: absolute; top: 50%; transform: translateY(-50%); }`. [S1]
- **Both axes (absolute)**: `.center { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); }`. [S1]
- **Both axes (flexbox)**: `.center { display: flex; justify-content: center; align-items: center; }`. [S1]

## 📖 세부 내용 (Details)
- Same container/technique structure as the general centering recipe, with `<button>Centered Button</button>` as the child instead of a `<p>`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **일반 중앙 정렬 레시피와 완전히 동일한 기법**: `[[HOWTO CSS Center Vertical]]`에서 사용된 세 가지 기법(absolute+translateY, absolute+translate 양축, flexbox)이 대상 요소만 텍스트에서 버튼으로 바뀐 채 그대로 재사용된다는 점이 확인됨 — 중앙 정렬 기법이 자식 요소의 종류와 무관하게 동작함을 보여줌. [S1]

## 🛠️ 적용 사례 (Applied in summary)
"Centered Button"이라는 버튼을 컨테이너 안에서 세로만, 또는 세로+가로 모두 중앙 정렬하는 예제가 원문에서 제시됨. [S1]

## 💻 코드 패턴 (Code patterns)
Centering a button — identical technique to centering any element (CSS):
```css
.container { height: 200px; position: relative; }
.center {
  position: absolute;
  top: 50%; left: 50%;
  transform: translate(-50%, -50%);
}
```
```html
<div class="container">
  <div class="center"><button>Centered Button</button></div>
</div>
```
