Antigravity Agent c24165b8bc refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조
에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게
[공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류.
문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인).

- Topic_Programming → Domain_Programming (내부 구조 보존)
- Topic_Graphic → Domain_Design
- Topic_Business → Domain_Product
- Topic_General → Domain_General
- _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning),
  Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing)
- 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서)
- 빈 폴더 정리 (memory/procedures)
- 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트)

W3CSS Navigation

🎯 한 줄 통찰 (One-line insight)

Padding on the navbar CONTAINER versus padding on each INDIVIDUAL link produces visually similar layouts but behaviorally different hover feedback — the source explicitly warns that container-level padding means links "do not get full padding on hover," revealing that hover-affordance area is determined by which element actually owns the padding, not just how the bar looks at rest. [S1]

🧠 핵심 개념 (Core concepts)

  • w3-bar fundamentals reused — this chapter is w3-bar/w3-bar-item/w3-bar-block applied specifically to navigation, plus w3-sidebar as a preview of the next chapter. [S1]
  • w3-hover-none + w3-hover-text-* — disables the default grey hover background and switches to a text-color-only hover effect instead. [S1]
  • Padding placement matters for hoverw3-padding-16 on each link gives full-padding hover feedback; the same padding on the parent bar does not. [S1]
  • w3-top / w3-bottom — wrapping a bar in a div with this class fixes it to the viewport top/bottom, persisting through scroll. [S1]
  • Collapsing pattern — replacing a full navbar with a single hamburger button (☰) on small screens via hide/show classes, previewing the Sidebar chapter's collapsible pattern. [S1]
  • Icon integration — Font Awesome fa fa-* classes drop directly into bar items (cross-referenced to the Icons chapter). [S1]

📖 세부 내용 (Details)

  • Custom-width, mobile-responsive links: <a href="#" class="w3-bar-item w3-button w3-mobile w3-green" style="width:33%">Home</a> — combined with w3-mobile to become 100% width on small screens. [S1]
  • Fixed-to-viewport bar: <div class="w3-top"><div class="w3-bar">...</div></div>. [S1]
  • Text-only hover effect: <a class="w3-bar-item w3-button w3-hover-none w3-text-grey w3-hover-text-white">Link 1</a>. [S1]
  • Navbar with input + button combo: <input type="text" class="w3-bar-item w3-input" placeholder="Search.."><a href="#" class="w3-bar-item w3-button w3-green">Go</a>. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • 바 전체 vs 개별 링크 패딩의 호버 차이: 바 컨테이너에 패딩을 주면 개별 링크가 호버 시 전체 패딩 영역을 갖지 못한다는 점이 원문에서 명시적으로 경고됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — w3-top으로 상단 고정 네비게이션 바를 만들고 작은 화면에서 햄버거 버튼으로 축소하는 조합이 실전 반응형 웹사이트 헤더의 대표 패턴이다. [S1]

💻 코드 패턴 (Code patterns)

Fixing a navigation bar to the top of the viewport (HTML/CSS):

<div class="w3-top">
  <div class="w3-bar w3-black">
    <a href="#" class="w3-bar-item w3-button">Home</a>
    <a href="#" class="w3-bar-item w3-button">Link 1</a>
  </div>
</div>
