# [[HOWTO CSS Fixed Footer]]

## 🎯 한 줄 통찰 (One-line insight)
`position: fixed; bottom: 0; left: 0; width: 100%;` pins the footer to the VIEWPORT, not the document — meaning it stays visible on screen even while the page scrolls, which is exactly what makes a "fixed footer" behaviorally different from a normal footer that simply sits at the end of page content and scrolls away with everything else. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`position: fixed`** — removes the element from normal flow and anchors it relative to the VIEWPORT (browser window), not the document, so it never scrolls out of view. [S1]
- **`bottom: 0; left: 0; width: 100%;`** — pins the fixed element to the bottom edge and stretches it the full viewport width. [S1]

## 📖 세부 내용 (Details)
- Full example: `.footer { position: fixed; left: 0; bottom: 0; width: 100%; background-color: red; color: white; text-align: center; } <div class="footer"><p>Footer</p></div>`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
없음 — 신규 레시피, 기존 문서와 모순되는 내용 없음.

## 🛠️ 적용 사례 (Applied in summary)
빨간 배경의 "Footer" 텍스트 바를 화면 하단에 고정하는 최소 예제가 원문에서 직접 제시됨. [S1]

## 💻 코드 패턴 (Code patterns)
Fixed footer pinned to the viewport bottom (CSS):
```css
.footer {
  position: fixed;
  left: 0;
  bottom: 0;
  width: 100%;
  background-color: red;
  color: white;
  text-align: center;
}
```
