let widthScreen = Dimensions.get('window').width;
let heightScreen = Dimensions.get('window').height;

type Props = {};
export default class StyleSheetPage extends Component {
    render() {
        return(
            
                
                
                内边距

var styles = StyleSheet.create({
   containerStyle: {
       width:widthScreen,
       height:heightScreen,

       backgroundColor:"#E6E6FA",
   },
   borderStyle: {
       margin:20,
       height:50,

       backgroundColor:'yellow',

       borderRadius:10,
       borderLeftColor:"green",
       borderTopWidth:1,
       borderLeftWidth:3,

       backgroundColor:'#FFF0F5',
   },
   fontStyle: {
       fontSize:20,
       fontStyle:'italic', // normal,italic,oblique

       color:"red",
       textAlign:'center', // center,left,right
       lineHeight:40,

       letterSpacing:5,
   },
   shadowStyle: {
       // 文字阴影偏移
       textShadowOffset: {width: 10, height: 10},
       // 文字阴影颜色
       textShadowColor: 'black',
       // 文字阴影圆角的大小
       textShadowRadius: 1.5,
   },
   decorationStyle: {
       // 'none', 'underline', 'line-through', 'underline line-through'
       textDecorationLine: 'underline',
       // 'solid', 'double', 'dotted', 'dashed'
       textDecorationStyle: 'solid',
       textDecorationColor: 'blue',
   }

       height:heightScreen,

       backgroundColor:"#E6E6FA",
   },
   textStyle: {
       margin:10,
       height:40,

       backgroundColor:'#FFF0F5',
   }
