# Set variable mode on a style

> Set a variable mode for a style

## `style.setVariableMode(collection, mode, options?)`

Apply a [variable mode](/designer/reference/variable-modes) to a style. Each variable mode belongs to a [variable collection](/designer/reference/variable-collections-overview). To apply a variable mode, you must provide the variable collection that belongs to the variable mode.

\


### Syntax

```typescript
 style.setVariableMode(
    collection: {{VARIABLE_COLLECTION}},
    mode: {{VARIABLE_MODE}},
    options?: {
      breakpointId?: {{BREAKPOINT_ID}},
      pseudoStateKey?: {{PSEUDO_STATE_KEY}}
    }
  ): Promise<null>;
```

### Parameters

* **collection**: *VariableCollection* - The [variable collection](/designer/reference/variable-collections-overview) that belongs to the variable mode.
* **mode**: *VariableMode* - The [variable mode](/designer/reference/variable-modes) to set.
* **options?**: *BreakpointAndPseudo* - An object that lets you filter properties by breakpoint and/or pseudo-state. (Optional)

  * **`BreakpointId`**: Identifies the responsive breakpoint to get styles for.
    ```typescript
    type BreakpointId = "xxl" | "xl" | "large" | "main" | "medium" | "small" | "tiny"
    ```

  * **`PseudoStateKey`**: Specifies a CSS pseudo-class to get styles for.
    ```typescript
    type PseudoStateKey = "noPseudo" | "nth-child(odd)" | "nth-child(even)" |
      "first-child" | "last-child" | "hover" | "active" |
      "visited" | "focus" | "focus-visible" | "focus-within" |
      "placeholder" | "empty" | "before" | "after"
    ```

### Returns

**Promise\<`null`>**

A Promise that resolves to `null`.

#

### Example

```typescript
// Get Selected Element
const selectedElement = await webflow.getSelectedElement()

    if (selectedElement?.styles) {
    // Get Styles
    const styles = await selectedElement.getStyles()
    const primaryStyle = styles[0] // Get the primary style

    // Get Variable Collection
    const variableCollection = await webflow.getDefaultVariableCollection()
    const variableModes = await variableCollection?.getAllVariableModes()
    const variableMode = variableModes[0]

    // Set Variable Mode
    if (primaryStyle && variableCollection) {
        await primaryStyle.setVariableMode(variableCollection, variableMode)
        console.log('Variable mode set successfully')
    }
}
```
