+# [[HTML Lists]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+HTML lists group related items as unordered (bulleted) lists, ordered (numbered) lists, or description lists that pair terms with their descriptions. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Unordered list (`<ul>`)** — a list of items where order does not matter; items show with bullet markers by default. Each item is an `<li>`. [S1]
+- **Ordered list (`<ol>`)** — a list where order matters; items show numbered by default. Each item is an `<li>`. [S1]
+- **List item (`<li>`)** — the element used for each item inside both `<ul>` and `<ol>`. [S1]
+- **Description list (`<dl>`)** — a list of terms with a description of each term, using `<dt>` for the term and `<dd>` for its description. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Container + item pattern** — both unordered and ordered lists wrap a series of `<li>` items in a single list container (`<ul>` or `<ol>`). [S1]
+- **Term/description pairing pattern** — a description list alternates `<dt>` (term) and `<dd>` (description) pairs inside `<dl>`. [S1]
+
+## 📖 세부 내용 (Details)
+**Unordered HTML List.** An unordered list starts with the `<ul>` tag. Each list item starts with the `<li>` tag. The list items will be marked with bullets (small black circles) by default. [S1]
+```html
+<ul>
+  <li>Coffee</li>
+  <li>Tea</li>
+  <li>Milk</li>
+</ul>
+```
+
+**Ordered HTML List.** An ordered list starts with the `<ol>` tag. Each list item starts with the `<li>` tag. The list items will be marked with numbers by default. [S1]
+```html
+<ol>
+  <li>Coffee</li>
+  <li>Tea</li>
+  <li>Milk</li>
+</ol>
+```
+
+**HTML Description Lists.** HTML also supports description lists. A description list is a list of terms, with a description of each term. The `<dl>` tag defines the description list, the `<dt>` tag defines the term (name), and the `<dd>` tag describes each term. [S1]
+```html
+<dl>
+  <dt>Coffee</dt>
+  <dd>- black hot drink</dd>
+  <dt>Milk</dt>
+  <dd>- white cold drink</dd>
+</dl>
+```
+
+**HTML List Tags.** [S1]
+
+| Tag | Description |
+|---|---|
+| `<ul>` | Defines an unordered list |
+| `<ol>` | Defines an ordered list |
+| `<li>` | Defines a list item |
+| `<dl>` | Defines a description list |
+| `<dt>` | Defines a term in a description list |
+| `<dd>` | Describes the term in a description list |
+
+## 🛠️ 적용 사례 (Applied in summary)
+The "Coffee / Tea / Milk" examples above are the canonical applied examples of each list type. No external project/commit applications found in the source.
+
+## 💻 코드 패턴 (Code patterns)
+Unordered list (HTML):
+```html
+<ul>
+  <li>Item</li>
+</ul>
+```
+Ordered list (HTML):
+```html
+<ol>
+  <li>Item</li>
+</ol>
+```
+Description list (HTML):
+```html
+<dl>
+  <dt>Term</dt>
+  <dd>Description</dd>
+</dl>
+```
+
+## ⚖️ 비교 및 선택 기준 (Comparison & decision criteria)
+- **Use `<ul>`** when the order of items does not matter (rendered with bullets). [S1]
+- **Use `<ol>`** when order matters (rendered with numbers). [S1]
+- **Use `<dl>`** when each item is a term paired with a description. [S1]
