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 Grid Intro

🎯 한 줄 통찰 (One-line insight)

The CSS Grid Layout Module offers a grid-based layout system with rows and columns, enabling complex, responsive two-dimensional layouts without using float or positioning. [S1]

🧠 핵심 개념 (Core concepts)

  • Grid Layout Module — offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use float or positioning. [S1]
  • Two-dimensional — CSS Grid is used for two-dimensional layout, with rows AND columns; CSS Flexbox is used for one-dimensional layout, with rows OR columns. [S1]
  • Grid Container — the parent element where display is set to grid or inline-grid. [S1]
  • Grid Items — the direct children of the grid container, which automatically become grid items. [S1]

🧩 추출된 패턴 (Extracted patterns)

  • Container + items model — set display: grid on the parent; direct children automatically become grid items. [S1]
  • Define columns on the containergrid-template-columns controls how many columns and their widths (e.g., auto auto auto for three equal columns). [S1]

📖 세부 내용 (Details)

The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use float or positioning. [S1]

Grid vs Flexbox CSS Grid is used for two-dimensional layout, with rows AND columns. CSS Flexbox is used for one-dimensional layout, with rows OR columns. [S1]

Grid Components A grid consists of two essential parts: [S1]

  1. Grid Container — the parent element where display is set to grid or inline-grid.
  2. Grid Items — direct children of the grid container that automatically become grid items.

Complete example [S1]

<html>
<head>
<style>
.container {
  display: grid;
  grid-template-columns: auto auto auto;
  background-color: dodgerblue;
  padding: 10px;
}
.container div {
  background-color: #f1f1f1;
  border: 1px solid black;
  padding: 10px;
  font-size: 30px;
  text-align: center;
}
</style>
</head>
<body>
<div class="container">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
</div>
</body>
</html>

The page also lists a CSS Grid properties table covering grid-related properties such as grid-template-columns, grid-template-rows, gap, grid-area, justify-content, and align-items, each with a brief description of its functionality. The full property-by-property table text was not captured verbatim from the source.

🛠️ 적용 사례 (Applied in summary)

The page's own complete example styles a .container with display: grid and grid-template-columns: auto auto auto, plus styled child <div> items. No external project/commit applications found in the source.

💻 코드 패턴 (Code patterns)

Make a three-column grid container (language: CSS):

.container {
  display: grid;
  grid-template-columns: auto auto auto;
}

⚖️ 비교 및 선택 기준 (Comparison & decision criteria)
