W3CSS Navigation
🎯 한 줄 통찰 (One-line insight)
Padding on the navbar CONTAINER versus padding on each INDIVIDUAL link produces visually similar layouts but behaviorally different hover feedback — the source explicitly warns that container-level padding means links "do not get full padding on hover," revealing that hover-affordance area is determined by which element actually owns the padding, not just how the bar looks at rest. [S1]
🧠 핵심 개념 (Core concepts)
w3-barfundamentals reused — this chapter isw3-bar/w3-bar-item/w3-bar-blockapplied specifically to navigation, plusw3-sidebaras a preview of the next chapter. [S1]w3-hover-none+w3-hover-text-*— disables the default grey hover background and switches to a text-color-only hover effect instead. [S1]- Padding placement matters for hover —
w3-padding-16on each link gives full-padding hover feedback; the same padding on the parent bar does not. [S1] w3-top/w3-bottom— wrapping a bar in a div with this class fixes it to the viewport top/bottom, persisting through scroll. [S1]- Collapsing pattern — replacing a full navbar with a single hamburger button (☰) on small screens via hide/show classes, previewing the Sidebar chapter's collapsible pattern. [S1]
- Icon integration — Font Awesome
fa fa-*classes drop directly into bar items (cross-referenced to the Icons chapter). [S1]
📖 세부 내용 (Details)
- Custom-width, mobile-responsive links:
<a href="#" class="w3-bar-item w3-button w3-mobile w3-green" style="width:33%">Home</a>— combined withw3-mobileto become 100% width on small screens. [S1] - Fixed-to-viewport bar:
<div class="w3-top"><div class="w3-bar">...</div></div>. [S1] - Text-only hover effect:
<a class="w3-bar-item w3-button w3-hover-none w3-text-grey w3-hover-text-white">Link 1</a>. [S1] - Navbar with input + button combo:
<input type="text" class="w3-bar-item w3-input" placeholder="Search.."><a href="#" class="w3-bar-item w3-button w3-green">Go</a>. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
- 바 전체 vs 개별 링크 패딩의 호버 차이: 바 컨테이너에 패딩을 주면 개별 링크가 호버 시 전체 패딩 영역을 갖지 못한다는 점이 원문에서 명시적으로 경고됨. [S1]
🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — w3-top으로 상단 고정 네비게이션 바를 만들고 작은 화면에서 햄버거 버튼으로 축소하는 조합이 실전 반응형 웹사이트 헤더의 대표 패턴이다. [S1]
💻 코드 패턴 (Code patterns)
Fixing a navigation bar to the top of the viewport (HTML/CSS):
<div class="w3-top">
<div class="w3-bar w3-black">
<a href="#" class="w3-bar-item w3-button">Home</a>
<a href="#" class="w3-bar-item w3-button">Link 1</a>
</div>
</div>
