# [[CSS Grid Container]]

## 🎯 한 줄 통찰 (One-line insight)
A grid container contains one or more grid items arranged in columns and rows; an element becomes a grid container by setting `display` to `grid` or `inline-grid`, and all its direct children automatically become grid items. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Grid container definition** — a grid container contains one or more grid items arranged in columns and rows. [S1]
- **Automatic grid items** — all direct child elements of a grid container automatically become grid items. [S1]
- **Two display modes** — set `display: grid` (block-level) or `display: inline-grid` (inline) to make the container. [S1]
- **Container-level properties** — alignment and sizing are controlled by container properties such as `justify-content`, `align-content`, `align-items`, `grid-template-columns`, `grid-template-rows`, `column-gap`, `row-gap`, `gap`, and `place-content`. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Declare the container first** — set `display: grid` (or `inline-grid`) before any grid-template or alignment property takes effect. [S1]
- **Alignment lives on the container** — `justify-content` aligns items horizontally; `align-content` aligns them vertically inside the container. [S1]

## 📖 세부 내용 (Details)
A grid container contains one or more grid items arranged in columns and rows. All direct child elements of a grid container automatically become grid items. An element becomes a grid container by setting the `display` property to `grid` or `inline-grid`. [S1]

**Block-level grid** — use `display: grid` to make a block-level grid container. [S1]
```css
.container {
  display: grid;
}
```

**Inline grid** — use `display: inline-grid` to make an inline grid container. [S1]
```css
.container {
  display: inline-grid;
}
```

**Grid Container Properties** [S1]

| Property | Description |
|----------|-------------|
| `align-content` | Vertically aligns the grid items inside the container |
| `align-items` | Specifies the default alignment for items inside a flexbox or grid container |
| `column-gap` | Specifies the gap between the columns |
| `gap` | A shorthand property for the `row-gap` and the `column-gap` properties |
| `grid-template-columns` | Specifies the size of the columns, and how many columns in a grid layout |
| `grid-template-rows` | Specifies the size of the rows in a grid layout |
| `justify-content` | Horizontally aligns the grid items inside the container |
| `row-gap` | Specifies the gap between the grid rows |
| `place-content` | A shorthand property for the `align-content` and the `justify-content` properties |

The page also presents interactive "Try it Yourself" examples demonstrating `justify-content` and `align-content` with various values; the literal CSS source for those alignment-value examples is only available behind the "Try it Yourself" buttons and was: Not found in source.
