# Styling the Navigator

You can style the navigator appearance and behavior by passing a `navigatorStyle` object. This object can be passed when the screen is originally created; can be defined per-screen by setting `static navigatorStyle = {};` on the screen component; and can be overridden when a screen is pushed.

The easiest way to style your screen is by adding `static navigatorStyle = {};` to your screen React component definition.

```js
export default class StyledScreen extends Component {
  static navigatorStyle = {
    drawUnderNavBar: true,
    navBarTranslucent: true
  };
  constructor(props) {
    super(props);
  }
  render() {
    return (
      <View style={{flex: 1}}>...</View>
     );
  }
```

#### Style object format

```js
{
  // Common
  navBarTextColor: '#000000', // change the text color of the title (remembered across pushes)
  navBarTextFontFamily: 'font-name', // Changes the title font
  navBarBackgroundColor: '#f7f7f7', // change the background color of the nav bar (remembered across pushes)

  navBarButtonColor: '#007aff', // Change color of nav bar buttons (eg. the back button) (remembered across pushes)
  navBarButtonFontSize: 20, // Change font size nav bar buttons (eg. the back button) (remembered across pushes)
  navBarButtonFontWeight: '500', // Change font weight nav bar buttons (eg. the back button) (remembered across pushes)

  navBarLeftButtonFontSize: 17, // Change font size of left nav bar button
  navBarLeftButtonColor: 'red', // Change color of left nav bar button
  navBarLeftButtonFontWeight: '400', // Change font weight of left nav bar button

  navBarRightButtonFontSize: 17, // Change font size of right nav bar button
  navBarRightButtonColor: 'blue', // Change color of right nav bar button
  navBarRightButtonFontWeight: '600', // Change font weight of right nav bar button

  navBarHidden: false, // make the nav bar hidden
  navBarHideOnScroll: false, // make the nav bar hidden only after the user starts to scroll
  navBarTranslucent: false, // make the nav bar semi-translucent, works best with drawUnderNavBar:true
  navBarTransparent: false, // make the nav bar transparent, works best with drawUnderNavBar:true,
  navBarNoBorder: false, // hide the navigation bar bottom border (hair line). Default false
  drawUnderNavBar: false, // draw the screen content under the nav bar, works best with navBarTranslucent:true
  drawUnderTabBar: false, // draw the screen content under the tab bar (the tab bar is always translucent)
  statusBarBlur: false, // blur the area under the status bar, works best with navBarHidden:true
  navBarBlur: false, // blur the entire nav bar, works best with drawUnderNavBar:true
  tabBarHidden: false, // make the screen content hide the tab bar (remembered across pushes)
  statusBarHideWithNavBar: false // hide the status bar if the nav bar is also hidden, useful for navBarHidden:true
  statusBarHidden: false, // make the status bar hidden regardless of nav bar state
  statusBarTextColorScheme: 'dark', // text color of status bar, 'dark' / 'light' (remembered across pushes)
  statusBarTextColorSchemeSingleScreen: 'light' // same as statusBarTextColorScheme but does NOT remember across pushes
  navBarSubtitleColor: 'red', // subtitle color
  screenBackgroundColor: 'white', // Default screen color, visible before the actual react view is rendered
  orientation: 'portrait' // Sets a specific orientation to a modal and all screens pushed to it. Default: 'auto'. Supported values: 'auto', 'landscape', 'portrait'
  
  // iOS only
  disabledBackGesture: false, // default: false. Disable the back gesture (swipe gesture) in order to pop the top screen.

  // Android only
  navigationBarColor: '#000000', // change the background color of the bottom native navigation bar.
  navBarTitleTextCentered: true, // default: false. centers the title.

}
```

## Styling the StatusBar
If you set any styles related to the Status Bar, make sure that in Xcode > project > Info.plist, the property `View controller-based status bar appearance` is set to `YES`.

## Custom fonts
If you'd like to use a custom font, you'll first have to your project.

* Android - add the `.ttf` or `.otf` files to `src/main/assets/fonts/`

* iOS - follow this [guide](https://medium.com/@dabit3/adding-custom-fonts-to-react-native-b266b41bff7f)

All supported styles are defined [here](https://github.com/wix/react-native-controllers#styling-navigation). There's also an example project there showcasing all the different styles.
