# [[CSS Padding]]

## 🎯 한 줄 통찰 (One-line insight)
The CSS padding properties generate space around an element's content, inside of any defined borders. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Definition** — Padding is used to generate space around an element's content, inside of any defined borders. [S1]
- **Four directional properties** — `padding-top`, `padding-right`, `padding-bottom`, and `padding-left` set padding on each side individually. [S1]
- **Accepted values** — length (px, pt, cm, etc.), percentage (% of the containing element's width), or `inherit`. Negative values are not permitted. [S1]
- **Shorthand** — the `padding` property lets you set all four sides in one declaration. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Per-side control vs. shorthand** — use individual `padding-*` properties for asymmetric spacing, or the `padding` shorthand when expressing several sides at once. [S1]
- **Clockwise shorthand order** — when four values are given, they apply top → right → bottom → left (clockwise from the top). [S1]

## 📖 세부 내용 (Details)
**What padding is**
The CSS padding properties are used to generate space around an element's content, inside of any defined borders. [S1]

**Individual side properties**
CSS provides four properties for setting the padding of each side of an element: [S1]
- `padding-top`
- `padding-right`
- `padding-bottom`
- `padding-left`

All the padding properties can accept the following values: a length (px, pt, cm, etc.), a percentage (% of the width of the containing element), or `inherit` (the padding is inherited from the parent element). Negative values are not allowed. [S1]

**The `padding` shorthand property**
To shorten the code, it is possible to specify all the padding properties in one property. The shorthand interprets its values by count: [S1]

If the `padding` property has **four** values — `padding: 25px 50px 75px 100px;` — then: [S1]
- top padding is `25px`
- right padding is `50px`
- bottom padding is `75px`
- left padding is `100px`
```css
div {
  padding: 25px 50px 75px 100px;
}
```

If the `padding` property has **three** values — `padding: 25px 50px 75px;` — then: [S1]
- top padding is `25px`
- right and left padding are `50px`
- bottom padding is `75px`
```css
div {
  padding: 25px 50px 75px;
}
```

If the `padding` property has **two** values — `padding: 25px 50px;` — then: [S1]
- top and bottom padding are `25px`
- right and left padding are `50px`
```css
div {
  padding: 25px 50px;
}
```

If the `padding` property has **one** value — `padding: 25px;` — then all four paddings are `25px`. [S1]
```css
div {
  padding: 25px;
}
```

## 🛠️ 적용 사례 (Applied in summary)
The shorthand declarations above are the page's own applied examples, showing how 1–4 values map to the four sides. No external project/commit applications found in the source.

## 💻 코드 패턴 (Code patterns)
Set padding per side (language: CSS):
```css
div {
  padding-top: 25px;
  padding-right: 50px;
  padding-bottom: 75px;
  padding-left: 100px;
}
```
Equivalent four-value shorthand:
```css
div {
  padding: 25px 50px 75px 100px;
}
```
