docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합
이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영. - Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들 (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거. - Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/ Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/ Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이 존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존). - Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/ JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동. - 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리. - Topic_Programming 최종 문서 수: 2784 → 3985.

# [[CSS Flexbox Intro]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
CSS Flexbox (the Flexible Box Layout module) is a one-dimensional layout model that arranges items horizontally or vertically inside a flex container in a flexible, responsive way. [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **What it is** — CSS Flexbox is short for the CSS Flexible Box Layout module; it is a layout model for arranging items (horizontally or vertically) within a container, in a flexible and responsive way. [S1]
|
||||
- **Flex container** — the parent element, made a flex container with `display: flex` (or `inline-flex`). [S1]
|
||||
- **Flex items** — the direct children of the container automatically become flex items. [S1]
|
||||
- **One- vs two-dimensional** — CSS Flexbox is used for a one-dimensional layout, with rows OR columns; CSS Grid is used for a two-dimensional layout, with rows AND columns. [S1]
|
||||
|
||||
## 🧩 추출된 패턴 (Extracted patterns)
|
||||
- **Container/item pattern** — declare `display: flex` on a parent; its direct children become arrangeable flex items automatically. [S1]
|
||||
- **One-dimensional choice** — reach for flexbox when laying out along a single axis (a row OR a column); reach for Grid for two-axis layouts. [S1]
|
||||
|
||||
## 📖 세부 내용 (Details)
|
||||
CSS Flexbox is short for the CSS Flexible Box Layout module. Flexbox is a layout model for arranging items (horizontally or vertically) within a container, in a flexible and responsive way. [S1]
|
||||
|
||||
Flexbox consists of: [S1]
|
||||
- **A Flex Container** — the parent element with `display: flex` or `inline-flex`. [S1]
|
||||
- **Flex Items** — the direct children that automatically become flex items. [S1]
|
||||
|
||||
**Flexbox vs Grid:** CSS Flexbox is used for a one-dimensional layout, with rows OR columns. CSS Grid is used for a two-dimensional layout, with rows AND columns. [S1]
|
||||
|
||||
**Example — a basic flex container with three items** [S1]
|
||||
```html
|
||||
<html>
|
||||
<head>
|
||||
<style>
|
||||
.container {
|
||||
display: flex;
|
||||
background-color: DodgerBlue;
|
||||
}
|
||||
|
||||
.container div {
|
||||
background-color: #f1f1f1;
|
||||
margin: 10px;
|
||||
padding: 20px;
|
||||
font-size: 30px;
|
||||
}
|
||||
</style>
|
||||
</head>
|
||||
<body>
|
||||
|
||||
<div class="container">
|
||||
<div>Item 1</div>
|
||||
<div>Item 2</div>
|
||||
<div>Item 3</div>
|
||||
</div>
|
||||
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
**CSS Flexbox properties / browser-support table:** Not found in source (a property reference table was not present in the fetched content for this intro page; the source links forward to the Flex Container, Flex Items, and Flex Responsive pages). [S1]
|
||||
|
||||
## 🛠️ 적용 사례 (Applied in summary)
|
||||
The page's applied example is a `.container` set to `display: flex` with a DodgerBlue background holding three styled `div` children ("Item 1", "Item 2", "Item 3"), which render in a horizontal row. No external project/commit applications found in the source.
|
||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
Make an element a flex container (language: CSS):
|
||||
```css
|
||||
.container {
|
||||
display: flex;
|
||||
}
|
||||
```
|
||||
Container with three items (language: HTML):
|
||||
```html
|
||||
<div class="container">
|
||||
<div>Item 1</div>
|
||||
<div>Item 2</div>
|
||||
<div>Item 3</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
## ⚖️ 비교 및 선택 기준 (Comparison & decision criteria)
|
||||
- **Flexbox** — one-dimensional layout (rows OR columns). Choose it for arranging items along a single axis flexibly and responsively. [S1]
|
||||
- **CSS Grid** — two-dimensional layout (rows AND columns). Choose it when you need to control both axes simultaneously. [S1]
|
||||
|
||||
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
||||
No contradictions found in the source.
