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 Alerts
🎯 한 줄 통찰 (One-line insight)
The source explicitly prefers the × HTML entity over the literal letter "X" for close buttons — a small but deliberate detail, since × renders as a proper multiplication-style cross symbol rather than relying on the letter X looking "close enough," making the close affordance visually distinct from actual text content. [S1]
🧠 핵심 개념 (Core concepts)
- No dedicated alert class — alerts are
w3-panel+ a STRONG (saturated) color, contrasted against Notes' PALE colors. [S1] - Semantic color convention — red (danger), yellow (warning), green (success), blue (information) — though any color can technically be used. [S1]
- Dismissible via inline
onclick—this.parentElement.style.display='none'on aw3-button w3-display-toprightspan containing×. [S1] ×preferred over literal "X" — explicitly recommended as the standard close-icon character. [S1]- Composable with rounding and cards —
w3-round/w3-round-large/w3-round-xxlargeorw3-card-4can be layered onto an alert panel. [S1]
📖 세부 내용 (Details)
- Strong-color alert (Danger):
<div class="w3-panel w3-red"><h3>Danger!</h3><p>Red often indicates a dangerous or negative situation.</p></div>. [S1] - Dismiss button:
<span onclick="this.parentElement.style.display='none'" class="w3-button w3-display-topright">×</span>. [S1] - Rounded alert:
<div class="w3-panel w3-green w3-round">. [S1] - Card-style alert:
<div class="w3-panel w3-yellow w3-card-4">. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
- 닫기 아이콘 권장사항: 닫기 버튼에는 문자 "X"보다 × HTML 엔티티가 선호된다는 점이 팁으로 명시됨. [S1]
🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — onclick 인라인 이벤트만으로 별도 JS 파일 없이 알림을 닫는 것이 경량 UI 인터랙션의 대표 사례다. [S1]
💻 코드 패턴 (Code patterns)
Dismissible alert using the × entity (HTML):
<div class="w3-panel w3-red w3-display-container">
<span onclick="this.parentElement.style.display='none'"
class="w3-button w3-display-topright">×</span>
<h3>Danger!</h3>
<p>Red often indicates a dangerous or negative situation.</p>
</div>
