```tsx
import { Flex } from '@dnb/eufemia'
render(<Flex.Item />)
```
`Flex.Item` is a building block for [CSS flexbox](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_flexible_box_layout) based layout of contents and components. Should be used in combination with [Flex.Container](/uilib/layout/flex/container/).
```jsx
import { Flex } from '@dnb/eufemia'
render(
<Flex.Container>
<Flex.Item>content</Flex.Item>
</Flex.Container>
)
```

- [Docs code](https://github.com/dnbexperience/eufemia/tree/main/packages/dnb-design-system-portal/src/docs/uilib/layout/flex/item/)
You can provide a `size` property with a number from 1 to 12 (can be changed in [Flex.Container](/uilib/layout/flex/container/) with the `sizeCount` property).
The number will be used to set the item size (a part of the container). It set a percentage unit and apply it on the item via CSS. When the container is tilled to 100%, the remaining items will wrap to a new row.
The number 6 results in 50%, while 12 results in 100%.
```tsx
render(
<Flex.Container>
<Flex.Item size={6}>uses 50% in width</Flex.Item>
<Flex.Item size={6}>uses 50% in width</Flex.Item>
</Flex.Container>
)
```
### Responsive size
You can also make sizes respond to media queries.
For doing so, provide a `size` property with an object containing [Media Query](/uilib/usage/layout/media-queries/) types. Each media size should contain number, like mentioned above.
```tsx
render(
<Flex.Container>
<Flex.Item
size={{
small: 12,
large: 6,
}}
>
uses 50% or 100% based on the screen size
</Flex.Item>
<Flex.Item
size={{
small: 12,
large: 6,
}}
>
uses 50% or 100% based on the screen size
</Flex.Item>
</Flex.Container>
)
```
You need to ensure that `flex-wrap: wrap` is set, so the remaining items wrap to a new row when needed. This is enabled by default in the [Flex.Container](/uilib/layout/flex/container/).
## Demos
```tsx
render(
<Flex.Container>
<Flex.Item>
<TestElement>FlexItem</TestElement>
</Flex.Item>
<Flex.Item>
<TestElement>FlexItem</TestElement>
</Flex.Item>
</Flex.Container>
)
```
### Basic `size` usage
With the default `sizeCount` of 12 parts.
<Examples.BasicSizeExample />
## Advanced `size` usage
The following example has a customized amount of 4 parts (`sizeCount`) as well as custom breakpoints and media queries.
