W3CSS Effects
🎯 한 줄 통찰 (One-line insight)
Effect classes and color classes are designed to STACK, not replace each other — combining w3-hover-opacity with any w3-hover-<color> class (e.g. w3-hover-red) produces a lighter/softer version of that hover color, meaning the effects system was built as a compositional layer on top of the existing color system rather than a standalone feature. [S1]
🧠 핵심 개념 (Core concepts)
- Opacity tiers —
w3-opacity-min(0.75),w3-opacity(0.6),w3-opacity-max(0.25) — three fixed transparency levels, no arbitrary values. [S1] - Grayscale tiers —
w3-grayscale-min(50%),w3-grayscale(75%),w3-grayscale-max(100%) — not supported in IE 11 and earlier. [S1] - Sepia tiers —
w3-sepia-min(50%),w3-sepia(75%),w3-sepia-max(100%) — also not supported in IE 11 and earlier. [S1] - Hover variants —
w3-hover-opacity,w3-hover-grayscale,w3-hover-sepia— apply the effect only on mouse-over, not by default. [S1] - Stacking hover-opacity with hover-color — combining
w3-hover-opacitywith aw3-hover-<color>class softens/lightens that hover color. [S1]
📖 세부 내용 (Details)
- Three opacity tiers on images:
<img src="image.jpg" class="w3-opacity-min"><img src="image.jpg" class="w3-opacity"><img src="image.jpg" class="w3-opacity-max">. [S1] - Hover-only effects:
<img src="image.jpg" class="w3-hover-opacity"><img src="image.jpg" class="w3-hover-grayscale"><img src="image.jpg" class="w3-hover-sepia">. [S1] - Combined hover color + opacity:
<div class="w3-border w3-hover-opacity w3-hover-red"><p>w3-hover-red with w3-hover-opacity</p></div>— produces a lighter red on hover thanw3-hover-redalone. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
- IE 11 호환성 경고: w3-grayscale 계열과 w3-sepia 계열 클래스 모두 IE 11 이하 버전에서 지원되지 않는다고 원문에 명시됨 — 구형 브라우저 지원이 필요한 프로젝트에서는 주의 필요. [S1]
🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — hover-opacity와 hover-color를 조합해 부드러운 호버 색상을 만드는 조합 기법이 실전 UI 디테일 작업의 대표 활용 사례다. [S1]
💻 코드 패턴 (Code patterns)
Stacking hover-opacity with a hover-color class for a softened hover effect (HTML/CSS):
<div class="w3-border w3-hover-opacity w3-hover-red">
<p>w3-hover-red with w3-hover-opacity</p>
</div>
