# BlockSpacer
BlockSpacer is used to create empty block space, typically when variable spacing is needed between multiple elements.

Note that you should favor BlockStack when spacing between all elements is the same.
### Basic BlockSpacer

```tsx
import {
  reactExtension,
  BlockSpacer,
  View,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return (
    <>
      <View border="base" padding="base">
        View
      </View>
      <BlockSpacer spacing="loose" />
      <View border="base" padding="base">
        View
      </View>
    </>
  );
}

```

```js
import {extension, BlockSpacer, View} from '@shopify/ui-extensions/checkout';

export default extension('purchase.checkout.block.render', (root) => {
  const blockSpacer = root.createComponent(View, undefined, [
    root.createComponent(View, {border: 'base', padding: 'base'}, 'View'),
    root.createComponent(BlockSpacer, {spacing: 'loose'}),
    root.createComponent(View, {border: 'base', padding: 'base'}, 'View'),
  ]);

  root.appendChild(blockSpacer);
});

```


## BlockSpacerProps

### BlockSpacerProps

### spacing
Adjust size of the spacer
### id
A unique identifier for the component.
### MaybeResponsiveConditionalStyle
A type that represents a value that can be a conditional style. The conditions are based on the viewport size.
We highly recommend using the `Style` helper which simplifies the creation of conditional styles.

To learn more check out the [conditional styles](/api/checkout-ui-extensions/components/utilities/stylehelper) documentation.
T | ConditionalStyle<T, ViewportSizeCondition>
### ConditionalStyle

### default
The default value applied when none of the conditional values
specified in `conditionals` are met.
### conditionals
An array of conditional values.
### ConditionalValue

### conditions
The conditions that must be met for the value to be applied. At least one
condition must be specified.
### value
The value that will be applied if the conditions are met.
### ViewportSizeCondition

### viewportInlineSize

### ViewportInlineSize

'small' | 'medium' | 'large'
### Spacing

'none' | 'extraTight' | 'tight' | 'base' | 'loose' | 'extraLoose'
## StyleHelper
Style is a helper for authoring conditional values for prop styles.

Write complex conditional styles based on one or more conditions, such as viewport sizes and interactive states, in a concise and expressive way.
### DocsStyle

### default
Sets an optional default value to use when no other condition is met.
### when
Adjusts the style based on different conditions. All conditions, expressed
as a literal object, must be met for the associated value to be applied.

The `when` method can be chained together to build more complex styles.
