# CheckoutAppearanceRules

> Swift Structure

**Structure**

Per-element style overrides for the checkout.

```swift theme={null}
struct CheckoutAppearanceRules
```

Each property targets one element of the hosted page. A rule overrides the values the element inherits from `CheckoutAppearanceVariables`. Leave a property `nil` to keep the checkout default for that element.

## Initializers

### init(destinationInput:receiptEmailInput:globalMessage:label:input:tab:primaryButton:)

Creates the rule set.

```swift theme={null}
init(destinationInput: CheckoutDestinationInputRule? = nil, receiptEmailInput: CheckoutReceiptEmailInputRule? = nil, globalMessage: CheckoutGlobalMessageRule? = nil, label: CheckoutLabelRule? = nil, input: CheckoutInputRule? = nil, tab: CheckoutTabRule? = nil, primaryButton: CheckoutPrimaryButtonRule? = nil)
```

### init(from:)

Inherited from `Decodable.init(from:)`.

```swift theme={null}
init(from decoder: any Decoder) throws
```
