Antigravity Agent e9cbf23ab5 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>
<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>

🛠️ 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):

.container {
  display: flex;
}

<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)
