docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동

최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

+# [[W3CSS Animate]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Every directional slide-in animation (`w3-animate-top/bottom/left/right`) shares the exact same distance parameter (-300px to 0) regardless of direction — a single consistent "travel distance" convention across four otherwise-independent classes, which means combining them on sibling elements (as in the "Fade All" example with 4 images) produces a synchronized, evenly-timed multi-directional entrance effect for free. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`w3-animate-top` / `-bottom` / `-left` / `-right`** — slide an element in from that direction, travel distance always -300px to 0. [S1]
+- **`w3-animate-opacity`** — fades an element's opacity from 0 to 1 over 0.8 seconds (fade-in only, one-shot). [S1]
+- **`w3-animate-zoom`** — scales an element from 0% to 100% size. [S1]
+- **`w3-animate-fading`** — continuously fades in AND out on a repeating ~10-second cycle (the only class here that loops infinitely; all others are one-shot). [S1]
+- **`w3-spin`** — spins an element a full 360 degrees. [S1]
+- All animation classes are pure CSS (no JavaScript needed) — applied simply by adding the class name. [S1]
+
+## 📖 세부 내용 (Details)
+- Slide in from top: `<div class="w3-container"><h1 class="w3-center w3-animate-top">Animation is Fun!</h1></div>`. [S1]
+- Fade in: `<div class="w3-animate-opacity">..</div>`. [S1]
+- Continuous fade in/out loop: `<div class="w3-animate-fading">..</div>` — distinct from `w3-animate-opacity`, which only fades in once. [S1]
+- Combining four different directional animations on four images simultaneously: `<img class="w3-animate-top" src="img_01.jpg"><img class="w3-animate-zoom" src="img_02.jpg"><img class="w3-animate-left" src="img_03.jpg"><img class="w3-animate-bottom" src="img_04.jpg">`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **w3-animate-opacity vs w3-animate-fading의 차이**: 전자는 0→1로 한 번만 페이드인하고 끝나지만, 후자는 0→1→0을 약 10초 주기로 무한 반복한다는 점이 구분되어야 함. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 서로 다른 방향의 슬라이드 애니메이션을 여러 이미지에 동시 적용해 입체적인 등장 효과를 만드는 조합이 실전 활용의 대표 사례다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Combining different directional animations on multiple elements (HTML/CSS, no JS needed):
+```html
+<img class="w3-animate-top" src="img_01.jpg">
+<img class="w3-animate-zoom" src="img_02.jpg">
+<img class="w3-animate-left" src="img_03.jpg">
+<img class="w3-animate-bottom" src="img_04.jpg">
+```
