# Layout System

Naive UI provides a comprehensive layout system including CSS Grid-based layout, Flexbox, Space, and Layout components for building responsive page structures.

## When to Use

- Creating responsive grid layouts
- Building page structures with header, sidebar, content, and footer
- Implementing flexible layouts with Flexbox
- Adding consistent spacing between elements

---

## Grid System (n-grid)

Naive UI uses a CSS Grid-based layout system with 24 columns by default.

### Basic Concepts

- **24-column system**: Default is 24 columns, configurable
- **CSS Grid**: Uses native CSS Grid for layout
- **Responsive**: Supports responsive breakpoints
- **Flexible**: Items can span multiple columns

### Basic Grid

```vue
<template>
  <n-grid :cols="24">
    <n-gi :span="24">Full width</n-gi>
  </n-grid>
  
  <n-grid :cols="24">
    <n-gi :span="12">Half width</n-gi>
    <n-gi :span="12">Half width</n-gi>
  </n-grid>
  
  <n-grid :cols="24">
    <n-gi :span="8">One third</n-gi>
    <n-gi :span="8">One third</n-gi>
    <n-gi :span="8">One third</n-gi>
  </n-grid>
</template>
```

### Grid with Gaps

```vue
<template>
  <n-grid :cols="4" :x-gap="12" :y-gap="8">
    <n-gi v-for="i in 8" :key="i">
      <div class="item">{{ i }}</div>
    </n-gi>
  </n-grid>
</template>
```

### Responsive Grid

```vue
<template>
  <n-grid :cols="4" responsive="screen">
    <n-gi :span="4" :xs="24" :sm="12" :md="8" :lg="6" :xl="4">
      Responsive item
    </n-gi>
  </n-grid>
</template>
```

### Grid Item Offset

```vue
<template>
  <n-grid :cols="24">
    <n-gi :span="6" :offset="6">Offset by 6</n-gi>
  </n-grid>
</template>
```

### Grid Props

| Name | Description | Type | Default |
|------|-------------|------|---------|
| cols | Number of columns | `number \| string` | `24` |
| x-gap | Horizontal gap | `number \| string` | `0` |
| y-gap | Vertical gap | `number \| string` | `0` |
| responsive | Responsive mode | `'self' \| 'screen'` | `'self'` |
| collapsed | Collapsed state | `boolean` | `false` |
| collapsedRows | Rows when collapsed | `number` | `1` |

### Grid Item Props

## Flex Component (n-flex)

A flexible flexbox layout component.

### Basic Flex

```

### Flex with Justify

```vue
<template>
  <n-flex justify="center">
    <div>Centered</div>
  </n-flex>
  
  <n-flex justify="space-between">
    <div>Left</div>
    <div>Right</div>
  </n-flex>
</template>
```

### Flex Vertical

```vue
<template>
  <n-flex vertical>
    <div>Item 1</div>

```

### Flex Props

## Space Component (n-space)

Add consistent spacing between elements.

### Basic Space

```vue
<template>
  <n-space>
    <n-button>Button 1</n-button>
    <n-button>Button 2</n-button>
    <n-button>Button 3</n-button>
  </n-space>
</template>
```

### Space Sizes

```vue
<template>
  <n-space size="small">Small gap</n-space>
  <n-space size="medium">Medium gap</n-space>
  <n-space size="large">Large gap</n-space>
  <n-space :size="24">Custom 24px gap</n-space>
</template>
```

  <n-layout>
    <n-layout-header>Header</n-layout-header>
    <n-layout-content>Content</n-layout-content>
    <n-layout-footer>Footer</n-layout-footer>
  </n-layout>

```

### Collapsible Sidebar

```vue
<script setup>
import { ref } from 'vue'
const collapsed = ref(false)
</script>

<template>
  <n-layout has-sider>
    <n-layout-sider
      bordered
      collapse-mode="width"
      :collapsed-width="64"
      :width="240"
      :collapsed="collapsed"
      show-trigger
      @collapse="collapsed = true"
      @expand="collapsed = false"
    >
      Sidebar
    </n-layout-sider>
    <n-layout-content>Content</n-layout-content>

## Responsive Breakpoints

Naive UI uses default breakpoints for responsive design:

| Breakpoint | Screen Width |
|------------|--------------|
| `xs` | `< 640px` |
| `s` | `≥ 640px` |
| `m` | `≥ 1024px` |
| `l` | `≥ 1280px` |
| `xl` | `≥ 1536px` |
| `xxl` | `≥ 1920px` |

### Using Breakpoints

```vue
<template>
  <n-grid :cols="4" responsive="screen">
    <n-gi :span="1" :xs="4" :s="2" :m="1">
      Responsive grid item
    </n-gi>
  </n-grid>
</template>
```

## Best Practices

1. **Use Grid for 2D layouts**: Use `n-grid` when you need both rows and columns
2. **Use Flex for 1D layouts**: Use `n-flex` for single-row or single-column layouts
3. **Use Space for simple gaps**: Use `n-space` for consistent spacing between elements
4. **Layout composition**: Combine Layout components for full-page structures
5. **Responsive design**: Use responsive props for mobile-first design
6. **Collapsed sidebar**: Use `collapse-mode="width"` for better animation performance
