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.

W3CSS Borders
🎯 한 줄 통찰 (One-line insight)
A border can be made "invisible" yet still functional as a hover trigger — setting border:16px solid white on an element paired with w3-hover-border-green creates a thick border that's visually undetectable against a white background until hovered, at which point it visibly appears in green, a trick that relies on the border occupying space without being seen. [S1]
🧠 핵심 개념 (Core concepts)
w3-border/w3-border-{top,right,bottom,left}— adds borders to specific sides;w3-border-0removes all borders. [S1]w3-border-COLOR— sets border color (e.g.w3-border-red). [S1]w3-round-{small,large,xlarge,xxlarge}— rounds border corners at different intensities; plainw3-roundis the default rounding. [S1]w3-topbar/w3-bottombar/w3-leftbar/w3-rightbar— add THICK single-side borders (heavier than normalw3-border-*). [S1]w3-hover-border-COLOR— changes border color specifically on mouse hover. [S1]- Invisible-until-hover border trick — a white/matching-background border becomes visible only on hover via
w3-hover-border-*. [S1]
📖 세부 내용 (Details)
- Directional borders:
<div class="w3-panel w3-border-left"><p>I have only a left border.</p></div>. [S1] - Colored border:

<div style="border:16px solid white" class="w3-panel w3-hover-border-green"><p>Thick (invisible) border that turns green on hover.</p></div>. [S1]

🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 배경과 같은 색의 두꺼운 테두리를 호버 시에만 드러내는 트릭이 UI 인터랙션 디자인의 대표 실전 사례다. [S1]
