# [[CSS Icons Bootstrap]]

## 🎯 한 줄 통찰 (One-line insight)
Bootstrap glyphicons can be added to a page by linking the Bootstrap CDN stylesheet in the `<head>` and placing `<i>` elements with `glyphicon glyphicon-*` class names — no download or installation required. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Icon library approach** — icons can be added from the Bootstrap icon library (glyphicons). [S1]
- **CDN-based** — to use the Bootstrap glyphicons, add the Bootstrap CSS link inside the `<head>` section. [S1]
- **No installation** — no downloading or installation is required. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Stylesheet link in head** — reference the Bootstrap CDN stylesheet in `<head>` to enable glyphicons. [S1]
- **Two-class naming** — each icon uses the base class `glyphicon` plus a specific `glyphicon-<name>` class on an `<i>` element. [S1]

## 📖 세부 내용 (Details)
**Bootstrap Icons** — to use the Bootstrap glyphicons, add the following line inside the `<head>` section of your HTML page: [S1]
```html
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
```

**Note:** No downloading or installation is required! [S1]

**Example — adding Bootstrap glyphicons:** [S1]
```html
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
</head>
<body>

<i class="glyphicon glyphicon-cloud"></i>
<i class="glyphicon glyphicon-remove"></i>
<i class="glyphicon glyphicon-user"></i>
<i class="glyphicon glyphicon-envelope"></i>
<i class="glyphicon glyphicon-thumbs-up"></i>

</body>
</html>
```

Each icon is rendered by an `<i>` element carrying `glyphicon` together with a specific icon class (e.g. `glyphicon-cloud`, `glyphicon-remove`, `glyphicon-user`, `glyphicon-envelope`, `glyphicon-thumbs-up`). [S1]

## 🛠️ 적용 사례 (Applied in summary)
The page's own example renders five glyphicons (cloud, remove, user, envelope, thumbs-up) by linking the Bootstrap CDN stylesheet and adding inline `<i>` elements. No external project/commit applications found in the source.

## 💻 코드 패턴 (Code patterns)
Single Bootstrap glyphicon (language: HTML):
```html
<i class="glyphicon glyphicon-cloud"></i>
```
Required head reference:
```html
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
```
