HOWTO CSS Sidenav Buttons
🎯 한 줄 통찰 (One-line insight)
Each link starts positioned OFF-SCREEN (left: -80px, wider than the link's own visible width) rather than hidden via display: none or opacity: 0 — this specific choice is what allows the transition: 0.3s combined with :hover { left: 0; } to produce a smooth SLIDE-IN motion (the browser animates the left property's numeric change) instead of an instant appear/disappear, which opacity or display toggles could never animate the same way. [S1]
🧠 핵심 개념 (Core concepts)
- Off-screen starting position —
left: -80px(each tab's width is100px, so-80pxleaves a 20px sliver visible as a "handle"). [S1] transition: 0.3s— animates theleftproperty change smoothly, rather than snapping instantly. [S1]:hover { left: 0; }— slides the tab fully into view on hover. [S1]- Stacked
topoffsets + individual colors per tab — each of the four tabs (#about,#blog,#projects,#contact) has its owntopvalue (20px, 80px, 140px, 200px) and background color, positioning them as a vertically-stacked column of colored tabs. [S1] border-radius: 0 5px 5px 0— rounds only the RIGHT corners (top-right, bottom-right), since the left edge is meant to be flush against/hidden by the screen edge. [S1]
📖 세부 내용 (Details)
#mySidenav a { position: absolute; left: -80px; transition: 0.3s; width: 100px; border-radius: 0 5px 5px 0; } #mySidenav a:hover { left: 0; } #about { top: 20px; background-color: #04AA6D; }. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
- display/opacity 토글이 아니라 위치 애니메이션으로 슬라이드 효과를 냄: 다른 hover-reveal 레시피(예:
[[HOWTO CSS Button Split]])가display: none → block으로 즉시 나타나는 방식이었다면, 이 레시피는 요소를 화면 밖(left: -80px)에 미리 배치해두고transition으로 위치를 부드럽게 이동시킨다는 점이 확인됨 — display 토글은 애니메이션이 불가능하지만 위치(left) 값은 transition으로 애니메이션 가능하기 때문. [S1]
🛠️ 적용 사례 (Applied in summary)
About/Blog/Projects/Contact 4개의 색이 다른 탭이 화면 왼쪽에 살짝만 보이다가, 마우스를 올리면 부드럽게 미끄러져 나오는 예제가 원문에서 직접 제시됨. [S1]
💻 코드 패턴 (Code patterns)
Off-screen tabs that slide in smoothly via transition (CSS):
#mySidenav a {
position: absolute;
left: -80px; /* off-screen, 20px sliver visible */
transition: 0.3s;
width: 100px;
border-radius: 0 5px 5px 0;
}
#mySidenav a:hover {
left: 0; /* slides fully into view */
}
