# [[CSS Text Effects]]

## 🎯 한 줄 통찰 (One-line insight)
CSS text-effect properties control how text behaves at its boundaries — signaling overflow (`text-overflow`), breaking long words (`word-wrap`/`word-break`), and orienting lines horizontally or vertically (`writing-mode`). [S1]

## 🧠 핵심 개념 (Core concepts)
- **`text-overflow`** — specifies how overflowed content that is not displayed should be signaled to the user. [S1]
- **`text-overflow` prerequisites** — it relies on `white-space: nowrap;` and `overflow: hidden;` being set. [S1]
- **`word-wrap`** — allows long words to be broken and wrapped onto the next line. [S1]
- **`word-break`** — specifies line breaking rules for non-CJK scripts; values include `normal`, `break-all`, and `keep-all`. [S1]
- **`writing-mode`** — specifies whether lines of text are laid out horizontally or vertically. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Overflow-signal pattern** — `white-space: nowrap; overflow: hidden; text-overflow: clip | ellipsis;`. [S1]
- **Long-word-wrap pattern** — `word-wrap: break-word;` to break unbreakable words. [S1]
- **Break-rule pattern** — `word-break: break-all;` to break at any character. [S1]
- **Orientation pattern** — `writing-mode: vertical-rl;` to lay text vertically. [S1]

## 📖 세부 내용 (Details)
**CSS Text Overflow** [S1]
The `text-overflow` property specifies how overflowed content that is not displayed should be signaled to the user. It works with `white-space: nowrap;` and `overflow: hidden;`.

Clipped content:
```css
p.test1 {
  width: 200px;
  border: 1px solid #000000;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: clip;
}
```
Ellipsis:
```css
p.test2 {
  width: 200px;
  border: 1px solid #000000;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}
```

**CSS Word Wrapping** [S1]
The `word-wrap` property allows long words to be broken and wrapped onto the next line:
```css
p {
  word-wrap: break-word;
}
```

**CSS Word Breaking** [S1]
The `word-break` property specifies line breaking rules:
```css
p.test1 {
  word-break: normal;
}

p.test2 {
  word-break: break-all;
}
```

**CSS Writing Mode** [S1]
The `writing-mode` property specifies whether lines of text are laid out horizontally or vertically:
```css
p.test1 {
  writing-mode: horizontal-tb;
}

span {
  writing-mode: vertical-rl;
}

p.test2 {
  writing-mode: vertical-rl;
}
```

**CSS Text Effect Properties reference** [S1]
The page includes a table listing the text-effect properties: `text-justify`, `text-overflow`, `word-break`, `word-wrap`, and `writing-mode`, each with a brief description of its function.

## 🛠️ 적용 사례 (Applied in summary)
The page's own demonstrations (`p.test1`/`p.test2`, `span`, and `p` elements showing clip/ellipsis overflow, word wrapping, word breaking, and writing modes) serve as the applied examples. No external project/commit applications found in the source.

## 💻 코드 패턴 (Code patterns)
Truncate with ellipsis (language: CSS):
```css
p.test2 {
  width: 200px;
  border: 1px solid #000000;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}
```
Break long words:
```css
p {
  word-wrap: break-word;
}
```
Vertical text:
```css
span {
  writing-mode: vertical-rl;
}
```

## ⚖️ 비교 및 선택 기준 (Comparison & decision criteria)
- **`text-overflow: clip` vs `ellipsis`** — `clip` simply cuts off the overflowed text; `ellipsis` signals the truncation with a "…". Both require `white-space: nowrap;` and `overflow: hidden;`. [S1]
- **`word-wrap` vs `word-break`** — `word-wrap: break-word` breaks long words only when needed to wrap; `word-break: break-all` breaks between any characters. [S1]
- **`writing-mode` horizontal-tb vs vertical-rl** — choose `horizontal-tb` for normal horizontal flow and `vertical-rl` for vertically laid-out lines. [S1]
