# [[CSS Text Spacing]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
CSS provides five text-spacing properties — `text-indent`, `letter-spacing`, `line-height`, `word-spacing`, and `white-space` — to control indentation, character/word/line spacing, and whitespace handling. [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **`text-indent`** — specifies the indentation of the first line in a text-block; negative values are permitted for leftward indentation. [S1]
|
||||
- **`letter-spacing`** — specifies the space between the characters in a text; negative values are allowed. [S1]
|
||||
- **`line-height`** — specifies the space between lines; negative values are not permitted. [S1]
|
||||
- **`word-spacing`** — specifies the space between the words in a text; negative values are allowed. [S1]
|
||||
- **`white-space`** — specifies how whitespace inside an element is handled; values include `normal`, `nowrap`, `pre`, `pre-line`, and `pre-wrap`. [S1]
|
||||
|
||||
## 🧩 추출된 패턴 (Extracted patterns)
|
||||
- **First-line indent pattern** — `text-indent: <length>;` to indent the opening line of a block. [S1]
|
||||
- **Character/word tracking pattern** — adjust `letter-spacing` and `word-spacing` (including negative values) to tighten or loosen spacing. [S1]
|
||||
- **Line density pattern** — use unitless `line-height` (e.g., `0.8` vs `1.8`) for tighter or looser line spacing. [S1]
|
||||
- **No-wrap pattern** — `white-space: nowrap;` to prevent text from wrapping. [S1]
|
||||
|
||||
## 📖 세부 내용 (Details)
|
||||
The page discusses five CSS properties for controlling text spacing: `text-indent`, `letter-spacing`, `line-height`, `word-spacing`, and `white-space`. [S1]
|
||||
|
||||
**Text Indentation** — "The CSS `text-indent` property is used to specify the indentation of the first line in a text-block." Negative values are permitted for leftward indentation. [S1]
|
||||
```css
|
||||
p {
|
||||
text-indent: 50px;
|
||||
}
|
||||
```
|
||||
|
||||
**Letter Spacing** — "The CSS `letter-spacing` property is used to specify the space between the characters in a text." Negative values are allowed. [S1]
|
||||
```css
|
||||
h1 {
|
||||
letter-spacing: 5px;
|
||||
}
|
||||
|
||||
h2 {
|
||||
letter-spacing: -2px;
|
||||
}
|
||||
```
|
||||
|
||||
**Line Height** — "The CSS `line-height` property is used to specify the space between lines." Negative values are not permitted. [S1]
|
||||
```css
|
||||
p.small {
|
||||
line-height: 0.8;
|
||||
}
|
||||
|
||||
p.big {
|
||||
line-height: 1.8;
|
||||
}
|
||||
```
|
||||
|
||||
**Word Spacing** — "The CSS `word-spacing` property is used to specify the space between the words in a text." Negative values are allowed. [S1]
|
||||
```css
|
||||
p.one {
|
||||
word-spacing: 10px;
|
||||
}
|
||||
|
||||
p.two {
|
||||
word-spacing: -2px;
|
||||
}
|
||||
```
|
||||
|
||||
**White Space** — "The CSS `white-space` property specifies how white-space inside an element is handled." This property can accept values including `normal`, `nowrap`, `pre`, `pre-line`, and `pre-wrap`. [S1]
|
||||
```css
|
||||
p {
|
||||
white-space: nowrap;
|
||||
}
|
||||
```
|
||||
|
||||
A summary table on the page lists each property with its description, linking to detailed CSS reference documentation for each spacing attribute. [S1]
|
||||
|
||||
## 🛠️ 적용 사례 (Applied in summary)
|
||||
The page's own examples are the applied cases: first-line indentation, positive/negative letter spacing, tight vs loose line height, positive/negative word spacing, and a no-wrap whitespace rule. No external project/commit applications found in the source.
|
||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
Spacing properties (language: CSS):
|
||||
```css
|
||||
selector {
|
||||
text-indent: <length>;
|
||||
letter-spacing: <length>;
|
||||
line-height: <number | length>;
|
||||
word-spacing: <length>;
|
||||
white-space: normal | nowrap | pre | pre-line | pre-wrap;
|
||||
}
|
||||
```
|
||||
Concrete example:
|
||||
```css
|
||||
p.big {
|
||||
line-height: 1.8;
|
||||
}
|
||||
```
|
||||
