# [[CSS Navigation Bar]]

## 🎯 한 줄 통찰 (One-line insight)
A navigation bar is fundamentally a list of links built from `<ul>`/`<li>` elements, then stripped of its default bullets, margins, and padding so CSS can style it into a navbar. [S1]

## 🧠 핵심 개념 (Core concepts)
- **What it is** — a navigation bar is an important web-design component that helps users navigate between sections of a website. [S1]
- **Built from lists** — navbars are typically built with HTML list elements (`<ul>` and `<li>`) and then styled with CSS. [S1]
- **Placement** — navigation bars are typically located at the top or side of a webpage. [S1]
- **Navbar = list of links** — since a navbar is basically a list of links, `<ul>` and `<li>` are a natural fit. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Reset the list** — `list-style-type: none; margin: 0; padding: 0;` removes bullets and default browser spacing, giving a clean base for styling. [S1]
- **Shared base** — the same HTML+CSS base is reused for both vertical and horizontal navbars. [S1]

## 📖 세부 내용 (Details)
**Introduction** [S1]
A navigation bar is an important component of web design. Navigation bars help users navigate between different sections of a website. They are typically built with HTML list elements (`<ul>` and `<li>`), then styled with CSS. Navigation bars are typically located at the top or side of a webpage.

**Navigation Bar = List of Links** [S1]
A navigation bar is basically a list of links, so using the HTML `<ul>` and `<li>` elements makes perfect sense:
```html
<ul>
  <li><a href="default.asp">Home</a></li>
  <li><a href="news.asp">News</a></li>
  <li><a href="contact.asp">Contact</a></li>
  <li><a href="about.asp">About</a></li>
</ul>
```

Then strip the list of its default styling:
```css
ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
}
```

**Example explained** [S1]
- `list-style-type: none;` — Removes the bullet points from the list
- `margin: 0;` — Resets default browser margins
- `padding: 0;` — Resets default browser paddings

**Note** [S1]
The HTML and CSS code in the example above is the base code used for both vertical and horizontal navigation bars, which are covered in the next chapters.

## 🛠️ 적용 사례 (Applied in summary)
The page's applied example is the four-link `<ul>` (Home / News / Contact / About) reset with `list-style-type: none; margin: 0; padding: 0;` — the shared base for the vertical and horizontal navbar pages. No external project/commit applications found in the source.
