React Native Show SuperScript and SubScript

React Native SuperScript SubScript

React Native SuperScript SubScript is a React Native Version of tags available in HTML known as <sup> superscript and <sub> subscript.

Superscript tag sets the half of the character above on the text writing line like (10am) and the same as but in a different manner the Subscript tag is opposite of superscript, In subscript tag, the next character would be halfway down to the previous one like (10am).

lineHeight is a style attribute that will help us to make Superscript and Subscript text.

LineHeightText Type
30Shows normal Text
18Shows superscript
37Shows subscript

Here is a simple example to show how to show SuperScript and SubScript.

Show SuperScript Using

<Text style={{fontSize: 15, lineHeight: 18}}>am</Text>

Show SubScript Using

<Text style={{fontSize: 15, lineHeight: 37}}>am</Text>

In this example,  we will show a simple sentence that will have a SuperScript and SubScript text. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Code

Open App.js in any code editor and replace the code with the following code

App.js

//This is an example code to show SuperScript and SubScript//
import React, { Component } from 'react';
//import react in our code.
import { StyleSheet, Platform, View, Text } from 'react-native';
//import all the components we are going to use.

export default class Project extends Component {
  render() {
    return (
      <View style={styles.MainContainer}>
      {/*View to wrap multiple text*/}
        <View style={{flexDirection: 'row', alignItems: 'flex-start'}}>
        {/*View to wrap multiple text*/}
          <Text style={{fontSize: 20, lineHeight: 30}}>Time is 10</Text>
          {/*Superscript*/}
          <Text style={{fontSize: 15, lineHeight: 18}}>am</Text>
          <Text style={{fontSize: 20, lineHeight: 30}}> and I am late or the class</Text>
        </View>
        <View style={{flexDirection: 'row', alignItems: 'flex-start', marginTop:30}}>
        {/*View to wrap multiple text*/}
          <Text style={{fontSize: 20, lineHeight: 30}}>Time is 10</Text>
          {/*Subscript*/}
          <Text style={{fontSize: 15, lineHeight: 37}}>am</Text>
          <Text style={{fontSize: 20, lineHeight: 30}}> and I am late or the class</Text>
        </View>
      </View>
    );
  }
}
const styles = StyleSheet.create({
  MainContainer: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    paddingTop: Platform.OS === 'ios' ? 20 : 0,
    margin: 10,
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).
