border bottom react native
It seems borderBottom doesn't work for the Text component. You can either add a View wrapper and supply borderBottom to it or add a TextInput and make editable={false}
<View style={styles.headerWrapper}>
<Text style={styles.header}> Registration </Text>
</View>
...
headerWrapper: {
borderBottomColor: 'red',
borderBottomWidth: 2,
marginBottom: 30,
},
header: {
fontSize: 36,
alignSelf: 'auto',
color: 'red',
},
