# [[CSS Outline Width]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
The `outline-width` property specifies the width of an outline, set either as a keyword (`thin`, `medium`, `thick`) or as a specific size. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **Purpose** — the `outline-width` property specifies the width (thickness) of an outline. [S1]
|
|
- **Keyword values** — `thin` (typically 1px), `medium` (typically 3px), and `thick` (typically 5px). [S1]
|
|
- **Explicit size** — a specific size in px, pt, cm, em, etc. [S1]
|
|
|
|
## 🧩 추출된 패턴 (Extracted patterns)
|
|
- **Keyword vs. explicit** — use `thin`/`medium`/`thick` for quick relative sizing, or a length unit when an exact thickness is required. [S1]
|
|
- **Requires a style** — `outline-width` is only visible alongside a set `outline-style` (e.g., `solid`). [S1]
|
|
|
|
## 📖 세부 내용 (Details)
|
|
**Accepted values**
|
|
The `outline-width` property specifies the outline's dimensions with these accepted values: [S1]
|
|
- `thin` (typically 1px)
|
|
- `medium` (typically 3px)
|
|
- `thick` (typically 5px)
|
|
- a specific size in px, pt, cm, em, etc.
|
|
|
|
**Demo example** — demonstration of different outline widths, each class applying a different `outline-width` value to paragraphs styled with solid green outlines and 5px padding: [S1]
|
|
```css
|
|
p {
|
|
padding: 5px;
|
|
outline-style: solid;
|
|
outline-color: green;
|
|
}
|
|
|
|
p.ex1 {
|
|
outline-width: thin;
|
|
}
|
|
|
|
p.ex2 {
|
|
outline-width: medium;
|
|
}
|
|
|
|
p.ex3 {
|
|
outline-width: thick;
|
|
}
|
|
|
|
p.ex4 {
|
|
outline-width: 8px;
|
|
}
|
|
```
|
|
|
|
## 🛠️ 적용 사례 (Applied in summary)

|
|
## 💻 코드 패턴 (Code patterns)
|
|
Set outline width by keyword or length (language: CSS):
|
|
```css
|
|
p.ex2 {
|
|
outline-style: solid;
|
|
outline-width: medium;
|
|
}
|
|
|
|
p.ex4 {
|
|
outline-style: solid;
|
|
outline-width: 8px;
|
|
}
|
|
```
