W3CSS Input
🎯 한 줄 통찰 (One-line insight)
w3-input has a bottom border by DEFAULT — the source frames "borderless" as the exception requiring an explicit w3-border-0 override, meaning W3.CSS's baked-in visual assumption is that text inputs should look like underlined fields (Material Design style) unless you deliberately opt out. [S1]
🧠 핵심 개념 (Core concepts)
w3-input— text input styling; has a bottom border BY DEFAULT (addw3-border-0to remove it, orw3-borderfor a full border). [S1]w3-animate-input— expands the input to 100% width specifically ON FOCUS (not permanently). [S1]w3-check— checkbox styling. [S1]w3-radio— radio button styling. [S1]w3-select— dropdown/select styling. [S1]- Label placement is purely structural — "Top Labels" vs. "Bottom Labels" is just whether the
<label>markup comes before or after the<input>in HTML order — no different classes involved. [S1] - Responsive Grid for form layout —
w3-row-padding+w3-third/w3-halflets multiple inputs sit on one row, stacking on small screens. [S1]
📖 세부 내용 (Details)
- Default bottom-border input:
<input class="w3-input" type="text">. [S1] - Borderless variant:
<input class="w3-input w3-border-0" type="text">. [S1] - Focus-expanding input:
<input class="w3-input w3-animate-input" type="text" style="width:30%">. [S1] - Checkbox with disabled state:
<input class="w3-check" type="checkbox" checked="checked"> <label>Milk</label> <input class="w3-check" type="checkbox" disabled> <label>Lemon (Disabled)</label>. [S1] - Radio group:
<input class="w3-radio" type="radio" name="gender" value="male" checked> <label>Male</label>. [S1] - Grid-based form layout:
<div class="w3-row-padding"><div class="w3-third"><input class="w3-input w3-border" type="text" placeholder="One"></div>...</div>. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
- 입력 필드 기본 테두리: w3-input이 기본적으로 하단 테두리를 가지며, 테두리 없는 형태는 w3-border-0으로 명시적으로 제거해야 한다는 점이 강조됨. [S1]
🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — Responsive Grid로 3개 입력 필드를 한 줄에 배치하는 것이 폼 레이아웃의 대표 실전 사례다. [S1]
💻 코드 패턴 (Code patterns)
Input focus animation expanding to full width (HTML):
<input class="w3-input w3-animate-input" type="text" style="width:30%">
