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 fromw3-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):
<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">
