+# [[CSS Font Family]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+The `font-family` property sets the typeface for text and should list several comma-separated font names as a fallback system, always ending with a generic family so the browser can pick the best available font. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Font selection matters** — choosing the right font has a huge impact on how readers experience a website; pick fonts that are easy to read with appropriate colors and sizes. [S1]
+- **`font-family` property** — specifies the font(s) for an element. [S1]
+- **Fallback system** — `font-family` should contain multiple font names so the browser can fall back if a font is unavailable. [S1]
+- **Comma-separated** — font names are separated by commas. [S1]
+- **Quote multi-word names** — font names made of more than one word require quotation marks. [S1]
+- **End with a generic family** — always end the list with a generic font family. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Fallback stack** — list specific fonts first, then progressively safer ones, ending in a generic family: `"Times New Roman", Times, serif`. [S1]
+- **Generic family classification** — group typefaces into five generic families: serif, sans-serif, monospace, cursive, fantasy. [S1]
+
+## 📖 세부 내용 (Details)
+**Font Selection is Important** — Choosing the right font has a huge impact on how the readers experience a website. The page stresses selecting fonts that are easy to read with appropriate colors and sizes. [S1]
+
+**The CSS `font-family` Property** — The `font-family` property specifies the font for an element. It should contain multiple font names as a "fallback" system: if the browser does not support the first font, it tries the next one. Font names are separated by commas, multi-word font names require quotation marks, and the list should always end with a generic family. [S1]
+
+Example with three fallback stacks: [S1]
+```css
+.p1 {
+  font-family: "Times New Roman", Times, serif;
+}
+
+.p2 {
+  font-family: Arial, Helvetica, sans-serif;
+}
+
+.p3 {
+  font-family: "Lucida Console", "Courier New", monospace;
+}
+```
+
+**CSS Generic Font Families** — five categories are listed: [S1]
+1. **Serif** fonts — formal and elegant.
+2. **Sans-serif** fonts — modern and minimalistic.
+3. **Monospace** fonts — mechanical appearance.
+4. **Cursive** fonts — imitate handwriting.
+5. **Fantasy** fonts — decorative / playful.
+
+**Font examples by generic family:** [S1]
+
+| Generic Family | Examples |
+|---|---|
+| Serif | Times New Roman, Georgia, Garamond |
+| Sans-serif | Arial, Verdana, Helvetica |
+| Monospace | Courier New, Lucida Console, Monaco |
+| Cursive | Brush Script MT, Lucida Handwriting |
+| Fantasy | Copperplate, Papyrus |
+
+**Note:** Sans-serif fonts are considered easier to read than serif fonts on computer screens. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+The page's example applies three different fallback stacks to three paragraph classes (`.p1`, `.p2`, `.p3`), each anchored by a different generic family (serif, sans-serif, monospace). No external project/commit applications found in the source.
+
+## 💻 코드 패턴 (Code patterns)
+Fallback stack pattern (language: CSS):
+```css
+selector {
+  font-family: "Specific Font", FallbackFont, generic-family;
+}
+```
+Concrete example:
+```css
+.p2 {
+  font-family: Arial, Helvetica, sans-serif;
+}
+```
+
+## ⚖️ 비교 및 선택 기준 (Comparison & decision criteria)
+The five generic families serve different stylistic intents: serif (formal/elegant), sans-serif (modern/minimalistic), monospace (mechanical, fixed-width), cursive (handwriting imitation), and fantasy (decorative/playful). Per the source note, sans-serif fonts are considered easier to read than serif fonts on screens, which guides the choice for body text on the web. [S1]

+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
