+# [[CSS Icons Google]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Google Material Icons can be added by linking the Material Icons stylesheet in the `<head>` and placing `<i class="material-icons">` elements whose text content is the icon name — no download or installation required. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Icon library approach** — icons can be added from the Google Material Icons library. [S1]
+- **Stylesheet-based** — to use the Google icons, add the Material Icons stylesheet 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 Google Material Icons font stylesheet in `<head>`. [S1]
+- **Name-as-text-content** — each icon uses the `material-icons` class on an `<i>` element with the icon name placed as the text content (e.g. `cloud`, `favorite`). [S1]
+
+## 📖 세부 내용 (Details)
+**Google Icons** — to use the Google icons, add the following line inside the `<head>` section of your HTML page: [S1]
+```html
+<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
+```
+
+**Note:** No downloading or installation is required! [S1]
+
+**Example — adding Google Material Icons:** [S1]
+```html
+<!DOCTYPE html>
+<html>
+<head>
+<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
+</head>
+<body>
+
+<i class="material-icons">cloud</i>
+<i class="material-icons">favorite</i>
+<i class="material-icons">attachment</i>
+<i class="material-icons">computer</i>
+<i class="material-icons">traffic</i>
+
+</body>
+</html>
+```
+
+Each icon is rendered by an `<i>` element with the `material-icons` class, and the icon name (e.g. `cloud`, `favorite`, `attachment`, `computer`, `traffic`) is placed as the text content of the tag. For the complete set of icons, the page refers readers to its Icon Tutorial. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+The page's own example renders five Material Icons (cloud, favorite, attachment, computer, traffic) by linking the Google stylesheet and adding inline `<i class="material-icons">` elements. No external project/commit applications found in the source.
+
+## 💻 코드 패턴 (Code patterns)
+Single Google Material icon (language: HTML):
+```html
+<i class="material-icons">cloud</i>
+```
+Required head reference:
+```html
+<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
+```
