# [[W3CSS Code]]

## 🎯 한 줄 통찰 (One-line insight)
Real syntax highlighting (`jsHigh`/`htmlHigh`/`cssHigh` classes) is explicitly NOT part of W3.CSS itself — it only activates if the developer separately downloads and includes W3Schools' own `w3codecolor.js` JavaScript library, meaning `w3-code`/`w3-codespan` alone only provide monospace STYLING, while color-coded syntax requires an entirely separate opt-in dependency. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`w3-code`** — displays a block of code in a readable monospaced font (pure CSS, no highlighting). [S1]
- **`w3-codespan`** — highlights inline code (e.g. within a sentence) using the `<code>` element. [S1]
- **`jsHigh` / `htmlHigh` / `cssHigh`** — color-highlighting classes that only function if `w3codecolor.js` is separately loaded; otherwise they have no visual effect. [S1]
- **Separation of styling vs. behavior** — this chapter reinforces a pattern seen elsewhere in W3.CSS: base classes are pure CSS, but advanced behavior (real syntax coloring) requires an external JS library, not baked into the CSS framework. [S1]

## 📖 세부 내용 (Details)
- Monospaced code block: `<div class="w3-code">fruits[0] = "Banana";</div>`. [S1]
- Inline code highlight: `The <code class="w3-codespan">html</code> element defines an HTML page.`. [S1]
- Requires external library for color: `<div class="w3-code jsHigh">.. JavaScript code here</div>` — only colors correctly once `w3codecolor.js` (downloadable from `w3schools.com/lib/w3codecolor.js`) is included on the page. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **w3-code만으로는 색상 강조 불가**: jsHigh/htmlHigh/cssHigh 클래스는 w3codecolor.js 라이브러리를 별도로 로드하지 않으면 아무 효과가 없다는 점이 명시적으로 경고됨. [S1]

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 이 문서 자체의 코드 패턴 섹션이 w3-code 클래스의 실전 활용 예시다. [S1]

## 💻 코드 패턴 (Code patterns)
Monospaced code display without syntax coloring (HTML/CSS):
```html
<div class="w3-code">
fruits[0] = "Banana";
fruits[1] = "Apple";
</div>
```
