HOWTO CSS Alert Buttons

🎯 한 줄 통찰 (One-line insight)

A shared .btn base class handles all the STRUCTURAL styling (border removal, padding, cursor) once, while five separate semantic modifier classes (.success, .info, .warning, .danger, .default) each carry ONLY a background-color pair (normal + :hover) — this base+modifier split means adding a sixth alert color later requires just one new 2-line modifier class, not a full button redefinition. [S1]

🧠 핵심 개념 (Core concepts)

Shared base class .btn — border: none; color: white; padding: 14px 28px; cursor: pointer; applied once to every alert button. [S1]
Color-coded semantic modifiers — .success (green), .info (blue), .warning (orange), .danger (red), .default (gray, with black text instead of white). [S1]
Each modifier defines its own :hover — a slightly darker shade of the same hue, applied consistently across all five variants. [S1]

📖 세부 내용 (Details)

HTML: <button class="btn success">Success</button> (and similarly for info/warning/danger/default). [S1]
CSS colors: success #04AA6D→hover #46a049; info #2196F3→hover #0b7dda; warning #ff9800→hover #e68a00; danger #f44336→hover #da190b; default #e7e7e7 (black text)→hover #ddd. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

없음 — 신규 레시피, 기존 문서와 모순되는 내용 없음.

🛠️ 적용 사례 (Applied in summary)

Success/Info/Warning/Danger/Default 5가지 색상의 알림 버튼을 하나의 공통 .btn 클래스와 색상별 수식 클래스로 구현하는 예제가 원문에서 직접 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Base class + semantic color modifiers (CSS):

.btn {
  border: none;
  color: white;
  padding: 14px 28px;
  cursor: pointer;
}
.success { background-color: #04AA6D; }
.success:hover { background-color: #46a049; }
.danger { background-color: #f44336; }
.danger:hover { background-color: #da190b; }
