# Customization

## Customizing Colors

To customize colors in `SnapFragment` use the `UIColorConfiguration` object on the Snapscreen instance.

```
Snapscreen.instance?.colorConfiguration.background = R.color.myBackground
```

## Customizing Fonts

To customize fonts in `SnapFragment`, use the `UIFontConfiguration` object on the Snapscreen instance.

```
Snapscreen.instance?.fontConfiguration.baseTypeface = Typeface.DEFAULT
```

## Customizing Snap UI

To customize displayed messages in the `SnapFragment` use the `SnapUIConfiguration` object on the Snapscreen instance.

```swift
Snapscreen.instance?.snapUIConfiguration.snapHintText = "My custom Hint"
```

All desired customizations must be done prior to presenting the  `SnapFragment` or `SnapActivity`. While it is possible to modify the configuration between presentations of the  `SnapFragment`, such modifications while `SnapFragment` is present are not guaranteed to be respected.
