# setRelativeWidth(_:withAdjustment:)

Sets the width of the object relative to its container.

```
func setRelativeWidth(_ width: CGFloat, withAdjustment adjustment: CGFloat)
```

## Parameters

`width`

The width of the object relative to its immediate container. This value represents the percentage of the container’s width. This value must be between `0.0` and `1.0`, and values outside of that range are clamped to the minimum or maximum value.

`adjustment`

The amount (in points) to add or subtract from the relative width. Positive values increase the width of the item and negative values decrease it.

## Discussion

You cannot use this method to alter the height of tables or separator items. Changes to the width of an object are animatable.
