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 Add Inline

🎯 한 줄 통찰 (One-line insight)

An inline style applies a unique style to a single element via its style attribute, but it loses many advantages of a style sheet by mixing content with presentation, so it should be used sparingly. [S1]

🧠 핵심 개념 (Core concepts)

Purpose — an inline style may be used to apply a unique style for a single element. [S1]
Mechanism — to use inline styles, add the style attribute to the relevant element. [S1]
Content — the style attribute can contain any CSS property declarations. [S1]
Caveat — an inline style loses many of the advantages of a style sheet (by mixing content with presentation); use this method sparingly. [S1]

🧩 추출된 패턴 (Extracted patterns)

Per-element override — attach declarations directly to one element via style="property:value;…". [S1]
Use sparingly — prefer external/internal sheets to keep content and presentation separate. [S1]

📖 세부 내용 (Details)

An inline style may be used to apply a unique style for a single element. To use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property. [S1]

<!DOCTYPE html>
<html>
<body>

<h1 style="color:blue;text-align:center;">This is a heading</h1>
<p style="color:red;">This is a paragraph.</p>

</body>
</html>

Here the <h1> element is given blue, center-aligned text, and the <p> element is given red text — all directly through their style attributes. [S1]

Tip: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly. [S1]
