HOWTO CSS About Page

🎯 한 줄 통찰 (One-line insight)

The team-card grid uses the OLDER float: left + width: 33.3% technique (not Flexbox/Grid) combined with the classic ::after { content: ""; clear: both; display: table; } clearfix on the row container — a reminder that this recipe predates (or intentionally avoids) the Grid & Flexbox recipes covered elsewhere in this cookbook, and that float-based column layouts still require the clearfix hack to prevent the container from collapsing to zero height. [S1]

🧠 핵심 개념 (Core concepts)

float: left columns — .column { float: left; width: 33.3%; } creates a 3-column grid without Flexbox/Grid. [S1]
Clearfix on the row — .container::after, .row::after { content: ""; clear: both; display: table; } prevents the floated columns from collapsing their parent's height. [S1]
box-sizing: border-box reset — applied globally via html { box-sizing: border-box; } *, *:before, *:after { box-sizing: inherit; }, so padding doesn't add to declared widths. [S1]
Responsive breakpoint — @media screen and (max-width: 650px) { .column { width: 100%; display: block; } } stacks the columns on narrow screens. [S1]

📖 세부 내용 (Details)

Structure: an .about-section intro block, followed by a .row of three .column > .card team-member blocks (image, name, title, bio, email, contact button). [S1]
Card styling: .card { box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2); margin: 8px; } gives each team member a subtle elevation effect. [S1]
Button hover: .button:hover { background-color: #555; }. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

없음 — 신규 레시피, 기존 문서와 모순되는 내용 없음.

🛠️ 적용 사례 (Applied in summary)

3명의 팀원 카드를 나열하는 "About Us" 페이지 레이아웃 전체가 원문에서 직접 실전 예제로 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Float-based 3-column layout with clearfix and a responsive breakpoint (CSS):

.column { float: left; width: 33.3%; padding: 0 8px; }
.row::after { content: ""; clear: both; display: table; }
@media screen and (max-width: 650px) {
  .column { width: 100%; display: block; }
}
