# [[HOWTO CSS Loading Buttons]]

## 🎯 한 줄 통찰 (One-line insight)
The entire "spinning" effect comes from Font Awesome's OWN `fa-spin` utility class, not any custom CSS animation authored in this recipe — `.buttonload` only handles the button's static look (background, padding, color), while the rotation itself is entirely delegated to whichever icon library is loaded, meaning this recipe demonstrates HOW to compose a third-party icon library's built-in animation utility with a custom button style, rather than teach `@keyframes` rotation from scratch. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`fa-spin`** — a Font Awesome utility class that rotates any icon continuously; combined with a spinner-shaped icon (`fa-spinner`, `fa-circle-o-notch`, `fa-refresh`) to create a loading indicator. [S1]
- **`.buttonload`** — only styles the button's static appearance (background/padding/color/font-size); contributes NOTHING to the spin animation itself. [S1]
- **Interchangeable spinner icons** — three different icon glyphs (`fa-spinner`, `fa-circle-o-notch`, `fa-refresh`) all combine with the SAME `fa-spin` class to produce visually different but functionally identical spinning loaders. [S1]

## 📖 세부 내용 (Details)
- `<button class="buttonload"><i class="fa fa-spinner fa-spin"></i>Loading</button>`. [S1]
- `.buttonload { background-color: #04AA6D; border: none; color: white; padding: 12px 16px; font-size: 16px; }`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
없음 — 신규 레시피, 기존 문서와 모순되는 내용 없음.

## 🛠️ 적용 사례 (Applied in summary)
서로 다른 스피너 아이콘 3개(spinner/circle-o-notch/refresh)를 fa-spin과 결합해 "Loading" 버튼 3종을 만드는 예제가 원문에서 직접 제시됨. [S1]

## 💻 코드 패턴 (Code patterns)
Loading button — animation comes entirely from the icon library's fa-spin utility (HTML + CSS):
```html
<button class="buttonload">
  <i class="fa fa-spinner fa-spin"></i>Loading
</button>
```
```css
.buttonload { background-color: #04AA6D; border: none; color: white; padding: 12px 16px; }
```
