# [[CSS Font Style]]

## 🎯 한 줄 통찰 (One-line insight)
Three CSS properties shape the appearance of a font: `font-style` (normal / italic / oblique), `font-weight` (thickness, keyword or numeric 100–900), and `font-variant` (normal / small-caps). [S1]

## 🧠 핵심 개념 (Core concepts)
- **`font-style`** — specifies text appearance with three values: normal (standard), italic (slanted), oblique (leaning, similar to italic). [S1]
- **`font-weight`** — controls character thickness: normal, bold, bolder, lighter, or the numeric scale 100–900 where 400 equals normal and 700 equals bold. [S1]
- **`font-variant`** — determines small-caps display: in a small-caps font, all lowercase letters are converted to uppercase letters but appear smaller than the original uppercase letters. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Class-per-style** — define a class for each desired style (`.normal`, `.italic`, `.oblique`) and apply the matching property value. [S1]
- **Numeric weight** — use the 100–900 numeric scale for fine-grained weight control (400 = normal, 700 = bold). [S1]

## 📖 세부 내용 (Details)
**CSS `font-style` property** — specifies the text appearance with three possible values: [S1]
- **normal** — standard text display.
- **italic** — slanted text styling.
- **oblique** — leaning text (similar to italic).

```css
p.normal {
  font-style: normal;
}

p.italic {
  font-style: italic;
}

p.oblique {
  font-style: oblique;
}
```

**CSS `font-weight` property** — controls character thickness with these options: normal (default, standard characters), bold (thick characters), bolder (thicker characters), lighter (lighter characters), and the numeric scale 100–900 where 400 equals normal and 700 equals bold. [S1]
```css
p.normal {
  font-weight: normal;
}

p.light {
  font-weight: lighter;
}

p.thick {
  font-weight: bold;
}

p.thicker {
  font-weight: 900;
}
```

**CSS `font-variant` property** — determines small-caps display. In a small-caps font, all lowercase letters are converted to uppercase letters, but they appear smaller than the original uppercase letters. [S1]
```css
p.normal {
  font-variant: normal;
}

p.small {
  font-variant: small-caps;
}
```

Each example includes a "Try it Yourself" interactive editor link for hands-on practice. [S1]

## 🛠️ 적용 사례 (Applied in summary)
The page's examples apply each property to paragraph classes — `font-style` to `.normal`/`.italic`/`.oblique`, `font-weight` to `.normal`/`.light`/`.thick`/`.thicker`, and `font-variant` to `.normal`/`.small`. No external project/commit applications found in the source.

## 💻 코드 패턴 (Code patterns)
Combined font styling (language: CSS):
```css
selector {
  font-style: italic;
  font-weight: 700;
  font-variant: small-caps;
}
```
Concrete numeric-weight example:
```css
p.thicker {
  font-weight: 900;
}
```
