# Space
Even though we have [Divider](/en-US/component/divider), but sometimes we need more than one [Divider](/en-US/component/divider) to split the elements apart, so we stack each elements upon [Divider](/en-US/component/divider), but doing so not only makes our code ugly but also makes it difficult to maintain. **Space** is this kind of component provides us both productivity and elegance.
## Basic usage
The basic use case is using this component to provide unified space between each components
:::demo Using Space to provide space
space/basic
:::
## Vertical layout
Using `direction` attribute to control the layout, we use `flex-direction` to implement this.
:::demo We also provide vertical layout.
space/vertical-layout
:::
## Control the size of the space
Control the space size via `size` API.
You can set the size with built-in sizes `small`, `default`, `large`, these size coresponds to `8px`, `12px`, `16px`. The default size is `small`, A.K.A. `8px`
You can also using customized size to override it. Refer to the next part.
:::demo
space/control-size
:::
## Customized Size
Sometimes built-in sizes could not meet the business needs, we can use custom size (number type) to control the space between items.
:::demo
space/customized-size
:::
:::tip
Do not use `ElSpace` with components that depend on ancestor width (height), e.g. `ElSlider`, in this case when you drag the trigger button the bar will grow which causes misplacement between cursor and trigger button.
:::
## Auto wrapping
When in **horizontal** mode, using `wrap` (**bool type**) to control auto wrapping behavior.
:::demo Using `wrap` to control line wrap
space/auto-wrapping
:::
## Spacer
Sometimes we want something more than blank space, so we have (spacer) to help us.
## Literal type spacer
:::demo
space/literal-type-spacer
:::
## Spacer can also be VNode
:::demo
space/vnode-type-spacer
:::
## Alignment
Setting this attribute can adjust the alignment of child nodes, the desirable value can be found at [align-items](https://developer.mozilla.org/en-US/docs/Web/CSS/align-items).
:::demo Using `alignment`
space/alignment
:::
## Fill the container
Through the `fill` **(Boolean type)** parameter, you can control whether the child node automatically fills the container.
In the following example, when set to `fill`, the width of the child node will automatically adapt to the width of the container.
:::demo Use fill to automatically fill the container with child nodes
space/fill
:::
You can also use the `fillRatio` parameter to customize the filling ratio. The default value is `100`, which represents filling based on the width of the parent container at `100%`.
It should be noted that the expression of horizontal layout and vertical layout is slightly different, the specific effect can be viewed in the following example.
:::demo Use fillRatio to customize the fill ratio
space/fill-ratio
:::
