# [[CSS Grid Intro]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
The CSS Grid Layout Module offers a grid-based layout system with rows and columns, enabling complex, responsive two-dimensional layouts without using float or positioning. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **Grid Layout Module** — offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use float or positioning. [S1]
|
|
- **Two-dimensional** — CSS Grid is used for two-dimensional layout, with rows AND columns; CSS Flexbox is used for one-dimensional layout, with rows OR columns. [S1]
|
|
- **Grid Container** — the parent element where `display` is set to `grid` or `inline-grid`. [S1]
|
|
- **Grid Items** — the direct children of the grid container, which automatically become grid items. [S1]
|
|
|
|
## 🧩 추출된 패턴 (Extracted patterns)
|
|
- **Container + items model** — set `display: grid` on the parent; direct children automatically become grid items. [S1]
|
|
- **Define columns on the container** — `grid-template-columns` controls how many columns and their widths (e.g., `auto auto auto` for three equal columns). [S1]
|
|

## 📖 세부 내용 (Details)
|
|
The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use float or positioning. [S1]
|
|
|
|
**Grid vs Flexbox**
|
|
CSS Grid is used for two-dimensional layout, with rows AND columns. CSS Flexbox is used for one-dimensional layout, with rows OR columns. [S1]
|
|
|
|
**Grid Components**
|
|
A grid consists of two essential parts: [S1]
|
|
1. **Grid Container** — the parent element where `display` is set to `grid` or `inline-grid`.
|
|
2. **Grid Items** — direct children of the grid container that automatically become grid items.
|
|
|
|
**Complete example** [S1]
|
|
```html
|
|
<html>
|
|
<head>
|
|
<style>
|
|
.container {
|
|
display: grid;
|
|
grid-template-columns: auto auto auto;
|
|
background-color: dodgerblue;
|
|
padding: 10px;
|
|
}
|
|
.container div {
|
|
background-color: #f1f1f1;
|
|
border: 1px solid black;
|
|
padding: 10px;
|
|
font-size: 30px;
|
|
text-align: center;
|
|
}
|
|
</style>
|
|
</head>
|
|
<body>
|
|
<div class="container">
|
|
<div>1</div>
|
|
<div>2</div>
|
|
<div>3</div>
|
|
<div>4</div>
|
|
<div>5</div>
|
|
</div>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
The page also lists a CSS Grid properties table covering grid-related properties such as `grid-template-columns`, `grid-template-rows`, `gap`, `grid-area`, `justify-content`, and `align-items`, each with a brief description of its functionality. The full property-by-property table text was not captured verbatim from the source.
|
|
|
|
## 🛠️ 적용 사례 (Applied in summary)
|
|
The page's own complete example styles a `.container` with `display: grid` and `grid-template-columns: auto auto auto`, plus styled child `<div>` items. No external project/commit applications found in the source.
|
|
|
|
## 💻 코드 패턴 (Code patterns)
|
|
Make a three-column grid container (language: CSS):
|
|
```css
|
|
.container {
|
|
display: grid;
|
|
grid-template-columns: auto auto auto;
|
|
}
|
|
```
