React Native styling tutorial with examples

Editor’s note: This article was last updated on 14 September 2023 to include information about customizing React Native components with StyleSheet.

As the demand for cross-platform mobile applications increases, so does the need for developers to adopt a single codebase for building apps that run on multiple operating systems.

Whether you aim to expand support for new platform users or reduce production costs, developing mobile apps that function on multiple devices is a wise approach. And when it comes to building cross-platform applications, React Native is a popular framework to do so.

In this tutorial, we will guide you through styling components in React Native. By building a sample e-commerce mobile application, we will demonstrate the various styling techniques in React Native that allow you to design effective cross-platform applications.

• A code editor installed in your development machine (e.g., VS Code)
• A basic understanding of React

An introduction to React Native

React Native is an open source mobile application framework that was launched by Facebook in 2015. Mobile developers worldwide use React Native to build apps for Android and iOS, as well as the web and macOS/Windows formats.

React Native’s key functions include:

• Employing the same design as React.js, which allows you to utilize the familiar React paradigm and components
• You can code using JavaScript
• React Native enables code reusability for both iOS and Android by writing the code once in most cases
• It renders UI using native components rather than WebViews, making your app truly native
• React Native apps compile their JavaScript code into optimized native app binaries, delivering blazing fast performance

The selling point of React Native is that it enables developers to use React’s framework along with native platform capabilities.

Setting up the environment

We are going to use Expo to quickly bootstrap a React Native project. To set up the development environment for an Expo project, you will need to first install Node.js and npm. This is required to run the create-expo-app command and install dependencies.

Then, create a new app called my-ecommerce-app using the create-expo-app command:

npx create-expo-app my-ecommerce-app

Next, navigate to the project directory:

cd my-ecommerce-app

Start the development server using the following command:

npx expo start

This command will start a Metro Bundler server and an Expo Dev Client that you can use to run the app on a physical device or in the web browser.

To run the app on a physical device, install the Expo Go app from the Play Store or App Store and scan the QR code from the terminal using the app. To run the app in a web browser, press w in the terminal. This will open the web app in your default browser.

Understanding React Native styling

Before we dive deeper into styling our app, let’s get a better understanding of React Native styling.

An app’s look and feel are directly connected to the user experience. Using platform-specific style guidelines for iOS and Android, following consistent typography, and even handling layout for multiple device sizes are very important to create an attractive, consistent, and intuitive app. These apps have a greater chance of users returning, which is an essential aspect of business.

React Native follows a CSS-in-JS approach for styling components instead of vanilla CSS. The syntax is very similar to what we are already familiar with in CSS, but let’s look at some key differences:

• React Native uses the flexbox layout API, instead of the CSS box model for layout. The flexbox API is better suited for mobile screens of different sizes and orientations
• In React Native, style properties are written as camelCased JavaScript properties instead of CSS syntax. For example, backgroundColor is written instead of background-color
• Instead of classes, styles are defined as JavaScript objects and applied using the style prop of components
• Animations are defined using JavaScript animation APIs instead of CSS transitions and animations. We can also use the React Native Reanimated package to write performant animations
• Vendor prefixes are not required because React Native handles platform-specific styling under the hood. But we can use the Platform API to handle different styles on different platforms
• Media queries are not supported by React Native. Responsiveness is achieved by defining different style sheets and conditionally applying them
• There are no :hover or :active pseudo-classes. We can use the Pressable component from React Native to handle styles for hover and active state:

  <Pressable
    style={({ pressed }) => [
      {
        backgroundColor: pressed ? "rgb(210, 230, 255)" : "white",
      },
    ]}
  >
    {({ pressed }) => (
      <Text style={styles.text}>{pressed ? "Pressed!" : "Press Me"}</Text>
    )}
  </Pressable>;
  

• There are some additional style properties specific to React Native, like borderRadius for rounded corners and flex for flexbox layout

Inline styles vs. StyleSheet

You can apply styles to a React Native component by either using inline styles or the StyleSheet.

Inline styles are used directly in the style prop of a component as a JavaScript object:

<Text style={{fontSize: 20, color: 'blue'}}>Hello LogRocket!</Text>

StyleSheet is used to create styles that are separate from React Native components. This approach makes it easier to maintain and reuse styles in multiple places:

// define styles
const styles = StyleSheet.create({
  text: {
    fontSize: 20, 
    color: 'blue'
  }
});

// use them in component
<Text style={styles.text}>Hello LogRocket!</Text>
// can also be reused
<Text style={styles.text}>This is a React Native tutorial</Text>

React Native styling properties and units

Units in React Native styles are a little different from CSS. React Native uses unitless numbers for properties like borderRadius, padding, fontSize, etc. For example, instead of saying 10px, we would just write 10, demonstrated as { fontSize: 10 }.

Units like dp, px etc., are added automatically based on the platform. This use of unitless numbers ensures that scaling occurs uniformly across devices with different resolutions.

Additionally, React Native supports percentage-based units, but they have to be provided inside a string like { width: '100%' }. When it comes to defining colors and alignment, you can apply them as usual, using string values.

Styling example with code walkthrough

For this React Native styling demo, we will build an e-commerce mobile application that displays various products for users to make orders based on their preferences. In particular, we’ll walk through building a landing page and cart functionality to highlight some key React Native styling concepts.

The finished application will look like this:

The e-commerce mobile application has two main functionalities built with two components: the Home component and the CartModal. To follow along, clone the starter repo here:

git clone https://github.com/iamshadmirza/logrocket-online-store.git

Navigate to the newly created log-rocket-online-store-starter directory and run npm install in your terminal/command prompt. Once installation is complete, run the command below to start the Metro bundler, which is a JavaScript bundler built by Facebook:

cd logrocket-online-store && npx expo start

If everything is set up correctly, you should have a new terminal window open, similar to the image below:

Now that we have our project set up and Metro bundler running, let’s run a build for our starter project.

Folder structure

The folder structure for our React Native styling example is as follows:

• assets contain all the application’s assets like images, icons, etc.
• constants contain images.ts, theme.ts, and index.ts. All assets are stored in JavaScript constants
• screens contains the Home.tsx and Home.finished.tsx files. Home.finished.tsx is for reference — it contains the final code
• src folder contains all of the above

In this tutorial, we’ll focus on styling the application and understanding when to use themes and when to use inline styling. Feel free to explore the codebase to understand how everything works behind the scenes.

Styling React Native components

The Home component has two sections: the featured product and recent searches.

Navigate to the screens directory. Here, you’ll find the boilerplate code in the Home component:

import React from "react";
import {
  StyleSheet,
  View,
  Text,
  FlatList,
  TouchableOpacity,
  Image,
  Modal,
} from "react-native";
import { BlurView } from 'expo-blur';
import { images, COLORS, SIZES, FONTS } from "../constants";
const Home = () => {
  const [selectedItem, setSelectedItem] = React.useState(null);
  const [selectedSize, setSelectedSize] = React.useState("");
  const [showAddToCartModal, setShowAddToCartModal] = React.useState(false);
  const [featured, setFeatured] = React.useState([
    {
      id: 0,
      name: "Jacket 4",
      img: images.jacket4,
      bgColor: "#D09040",
      price: "$250",
      type: "Featured",
      sizes: [6, 7, 8, 9, 10, 16],
    },
    {
      id: 1,
      name: "Jacket 1",
      img: images.jacket1,
      bgColor: "#D3D1C8",
      type: "Featured",
      price: "$150",
      sizes: [6, 7, 8, 9, 10, 12],
    },
    {
      id: 2,
      name: "Jacket 2",
      img: images.jacket2,
      type: "Featured",
      bgColor: "#303946",
      price: "$160",
      sizes: [6, 7, 8, 9, 10],
    },
  ]);
  const [recentSearches, setRecentSearch] = React.useState([
    {
      id: 0,
      name: "Jacket 4",
      img: images.jacket4,
      bgColor: "#D09040",
      price: "$250",
      type: "Featured",
      sizes: [6, 7, 8, 9, 10, 16],
    },
    {
      id: 1,
      name: "Sweater 3",
      img: images.sweater3,
      type: "Featured",
      bgColor: "#0F5144",
      price: "$100",
      sizes: [6, 7, 8, 9, 10, 16, 18],
    },
    {
      id: 2,
      name: "Sweater 5",
      img: images.sweater5,
      type: "Featured",
      bgColor: "#888983",
      price: "$100",
      sizes: [6, 7, 8, 9, 10, 18],
    },
    {
      id: 7,
      name: "Jacket 1",
      img: images.jacket1,
      bgColor: "#D3D1C8",
      type: "Featured",
      price: "$150",
      sizes: [6, 7, 8, 9, 10, 12],
    },
    {
      id: 8,
      name: "Jacket 2",
      img: images.jacket2,
      type: "Featured",
      bgColor: "#303946",
      price: "$160",
      sizes: [6, 7, 8, 9, 10],
    },
    {
      id: 3,
      name: "Hat 1",
      img: images.hat1,
      type: "Featured",
      bgColor: "#26232A",
      price: "$100",
      sizes: [6, 7, 8, 9, 10, 16],
    },
    {
      id: 4,
      name: "Shirt 1",
      img: images.shirt1,
      type: "Featured",
      bgColor: "#575569",
      price: "$100",
      sizes: [6, 7, 8, 9, 10, 16],
    },
    {
      id: 5,
      name: "Shirt 2",
      img: images.shirt2,
      type: "Featured",
      bgColor: "#2B3A6B",
      price: "$100",
      sizes: [6, 7, 8, 9, 10, 16],
    },
    {
      id: 6,
      name: "Shoe 1",
      img: images.shoe1,
      type: "Featured",
      bgColor: "#9E7348",
      price: "$100",
      sizes: [6, 7, 8, 9, 10, 12],
    },
  ]);

  function renderFeaturedItems(item, index) {
    return (
      <TouchableOpacity
        style={{
          height: 300,
          width: 200,
          justifyContent: "center",
          marginHorizontal: SIZES.base,
        }}
        onPress={() => {
          setSelectedItem(item);
          setShowAddToCartModal(true);
        }}
      >
        <Text style={{ color: COLORS.lightGray, ...FONTS.h5 }}>
          {item.type}
        </Text>
        <View
          style={[
            {
              flex: 1,
              justifyContent: "flex-end",
              marginTop: SIZES.base,
              borderRadius: 10,
              marginRight: SIZES.padding,
              backgroundColor: item.bgColor,
              paddingRight: SIZES.padding,
              paddingBottom: SIZES.radius,
            },
            style.featuredShadow,
          ]}
        >
          <View style={style.featuredDetails}>
            <Text
              style={{ color: COLORS.white, ...FONTS.body4, marginTop: 15 }}
            >
              {item.name}
            </Text>
            <Text style={{ color: COLORS.white, ...FONTS.h2 }}>
              {item.price}
            </Text>
          </View>
        </View>
        <Image
          source={item.img}
          resizeMode="cover"
          style={{
            position: "absolute",
            top: 25,
            right: 20,
            width: "90%",
            height: 200,
          }}
        />
      </TouchableOpacity>
    );
  }

  // paste recent searches code

  // paste renderSizes

  return (
    <View style={style.container}>
      <Text
        style={{
          marginTop: SIZES.radius,
          marginHorizontal: SIZES.padding,
          ...FONTS.h2,
        }}
      >
        FEATURED
      </Text>
      {/* Featured */}
      <View style={{ height: 260, marginTop: SIZES.radius }}>
        <FlatList
          horizontal
          showsHorizontalScrollIndicator={false}
          data={featured}
          keyExtractor={(item) => item.id.toString()}
          renderItem={({ item, index }) => renderFeaturedItems(item, index)}
        />
      </View>
      {/* Recent Searches */}

      {/* Modal */}
    </View>
  );
};
const style = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: COLORS.white,
  },
  featuredShadow: {
    shadowColor: "#000",
    shadowOffset: {
      width: 0,
      height: 5,
    },
    shadowOpacity: 0.29,
    shadowRadius: 4.65,
    elevation: 7,
  },
  featuredDetails: {
    position: "absolute",
    top: 160,
    left: 30,
    flexDirection: "column",
    marginLeft: 25,
    marginBottom: 8,
  },
});

export default Home;

If you run npm run ios, your app should now look like the image below:

Most of the font sizes, padding, and margins used above are declared in the theme.ts file located in the constant folder. Within the renderFeaturedItems function, notice that I combined inline styling and a prop approach to style the featured items. The react-native style prop accepts an array, so you can pass a second argument to style. See the example below:

style = {
  [{
      flex: 1,
      justifyContent: "flex-end",
      marginTop: SIZES.base,
      borderRadius: 10,
      marginRight: SIZES.padding,
      backgroundColor: item.bgColor,
      paddingRight: SIZES.padding,
      paddingBottom: SIZES.radius,
    },
    style.featuredShadow,
  ]
}

In the code block above, the style prop value is wrapped in a bracket [], meaning the prop will accept an array of objects as values. The second argument of the style prop is created using Stylesheet.create(). As stated earlier, this approach is popular in complex React Native applications and is an excellent way to support multiple styles.

Now that we’ve built the first section of the Home component, let’s build the last one: the recent searches section.

Before we begin, let’s consider what the recent searches structure should look like. We need to first create a flex container with its flex direction set to row, and two columns that will act as direct children of the container. The first column contains an image, the other is a flex container that houses the product image, product name, and price:

Like in CSS, when styling in React Native, you should always map your UI components to CSS properties before you begin styling your app. These will give you a broader overview of how to style your entire application from the ground up.

To build the second section of the Home component, find the // paste recent searches code comment and copy and paste the code beneath the comment:

 function renderRecentSearches(item, index) {
    return (
      <TouchableOpacity
        style={{ flex: 1, flexDirection: "row" }}
        onPress={() => {
          setSelectedItem(item);
          setShowAddToCartModal(true);
        }}
      >
        <View
          style={{ flex: 1, alignItems: "center", justifyContent: "center" }}
        >
          <Image
            source={item.img}
            resizeMode="contain"
            style={{
              width: 130,
              height: 100,
            }}
          />
        </View>
        <View
          style={{
            flex: 1.5,
            marginLeft: SIZES.radius,
            justifyContent: "center",
          }}
        >
          <Text>{item.name}</Text>
          <Text style={{ ...FONTS.h3 }}>{item.price}</Text>
        </View>
      </TouchableOpacity>
    );
  }

Next, find the {/* Recent Searches */} comment in Home.ts and paste the code below under it:

<View
    style={[
      {
        flex: 1,
        flexDirection: "row",
        marginTop: SIZES.padding,
        borderTopLeftRadius: 30,
        borderTopRightRadius: 30,
        backgroundColor: COLORS.white,
      },
      style.recentSearchShadow,
    ]}
  >
    <View style={{ width: 70, height: "100%", marginLeft: SIZES.base }}>
      <Image
        source={images.searches}
        style={{ width: "100%", height: "100%", resizeMode: "contain" }}
      />
    </View>
    <View style={{ flex: 1, paddingBottom: SIZES.padding }}>
      <FlatList
        showsVerticalScrollIndicator={false}
        data={recentSearches}
        keyExtractor={(item) => item.id.toString()}
        renderItem={({ item, index }) => renderRecentSearches(item, index)}
      />
    </View>
  </View>

Adding shadows

Adding shadows to a component in React Native is quite different from how it is done in CSS. You need to specify the shadowColor, ShadowOffset, ShadowOpacity, ShadowRadius and elevation.

Add the code below to StyleSheet.create to complete the styling of the recentSearches section of the Home component:

  recentSearchShadow:{
        shadowColor: "#000",
        shadowOffset:{
            width: 0,
            height: 5,
        },
        shadowOpacity: 0.29,
        shadowRadius: 4.65, 
        elevation: 7
    },
    recentSearches: {
        width: "100%",
        transform: [{ rotateY: "180deg" }]
    },

This only works to create a shadow in iOS. To add shadows to a component in Android, see the official instructions here.

Styling the modal

Finally, let’s create a modal to display each selected product. Find the // paste renderSizes comment in Home.tsx and copy and paste the following code underneath it:

function renderSizes() {
  return selectedItem.sizes.map((item, index) => {
    return (
      <TouchableOpacity
        key={index}
        style={{
          width: 35,
          height: 25,
          alignItems: "center",
          justifyContent: "center",
          marginHorizontal: 5,
          marginBottom: 10,
          backgroundColor:
            selectedItem.sizes[index] == selectedSize ? COLORS.white : null,
          borderWidth: 1,
          borderColor: COLORS.white,
          borderRadius: 5,
        }}
        onPress={() => {
          setSelectedSize(item);
        }}
      >
        <Text
          style={{
            color:
              selectedItem.sizes[index] == selectedSize
                ? COLORS.black
                : COLORS.white,
            ...FONTS.body4,
          }}
        >
          {item}
        </Text>
      </TouchableOpacity>
    );
  });
}

We need the blur effect in the modal background. Install the required package to use BlurView:

npx expo install expo-blur

Then you can import it like this:

import { BlurView } from 'expo-blur';

To add the modal when selectedItem is present, paste the following code beneath the comment {/* Modal */} in the Home component:

{selectedItem && (
  <Modal
    animationType="slide"
    transparent={true}
    visible={showAddToCartModal}
  >
    <BlurView
      style={style.blur}
      tint="light"
      intencity={20}
    >
      <TouchableOpacity
        style={style.absolute}
        onPress={() => {
          setSelectedItem(null);
          setSelectedSize("");
          setShowAddToCartModal(false);
        }}
      ></TouchableOpacity>
      {/* Modal content */}
      <View
        style={{
          justifyContent: "center",
          width: "85%",
          backgroundColor: selectedItem.bgColor,
        }}
      >
        <View>
          <Image
            source={selectedItem.img}
            resizeMode="contain"
            style={{
              width: "100%",
              height: 170,
            }}
          />
        </View>
        <Text
          style={{
            marginTop: SIZES.padding,
            marginHorizontal: SIZES.padding,
            color: COLORS.white,
            ...FONTS.h2,
          }}

          <View
            style={{

          >
            {renderSizes()}
          </View>
        </View>

        <TouchableOpacity
          style={{
            width: "100%",
            height: 70,
            justifyContent: "center",
            alignItems: "center",
            marginTop: SIZES.base,
            backgroundColor: "rgba(0,0,0,0.5)",
          }}
          onPress={() => {
            setSelectedItem(null);
            setSelectedSize("");
            setShowAddToCartModal(false);
          }}
        >
          <Text style={{ color: COLORS.white, ...FONTS.largeTitleBold }}>
            Add To Cart
          </Text>
        </TouchableOpacity>
      </View>
    </BlurView>
  </Modal>
)}

You have to use absolute positioning to position the modal in the center of the application. Copy and paste the code below into the Stylesheet.create() object to position the modal at the center:

blur: {
  flex: 1,
  alignItems: "center",
  justifyContent: "center",
},
absolute: {
  position: "absolute",
  top: 0,
  left: 0,
  right: 0,
  bottom: 0,
},

Once you’re happy with the code, you can compare it with the finished code available in the GitHub repository here.

Advanced styling techniques

Now that we have a solid foundation of basic styling in a React Native application, it’s time to explore some advanced techniques that can enhance the look and feel of your app. These techniques may not be supported directly by React Native out of the box, but they are crucial for creating a scalable and efficient styling solution.

Responsive design

• Use flexbox: React Native has a flexbox implementation similar to CSS. To create a responsive layout, you can use flex properties like flexDirection, flexWrap, alignItems, justifyContent, etc.
• Use the Dimensions API: React Native has a Dimensions API that gives you the width and height of the device screen. You can use this to render components based on screen size conditionally
• Use percent widths: Instead of fixed pixel widths, use percent widths for components. This will make them resize responsively based on screen width

Media queries

Media queries are not supported by default but we can use the react-native-media-queries package to get similar functionality:

import StyleSheet from 'react-native-media-query';
import { View, TextInput } from 'react-native'

const {ids, styles} = StyleSheet.create({
    example: {
        width: 100,
        height: 100,
        backgroundColor: 'green',
        '@media (max-width: 1600px) and (min-width: 800px)': {
            backgroundColor: 'red',
        },
        '@media (max-width: 800px)': {
            backgroundColor: 'blue',
        },
    },
    exampleTextInput: {
        paddingVertical: 27,
        backgroundColor: 'pink',
        '@media (max-width: 768px)': {
            paddingVertical: 13,
        },
        // example CSS selectors. these only work on web based platforms
        '::placeholder': {
            color: 'green',
        },
        ':hover': {
            backgroundColor: 'red',
        },
    }
})

Dynamic styling

Because React Native uses objects for styling, we can use any variable in place of the style of a property or we can use a function that returns some styles based a specific parameter:

const getBackgroundColor = (colorScheme) => {
    return colorScheme === 'dark' ? '#000' : '#fff'
}

<View style={getBackgroundColor("dark")} />

Theming

All modern apps now support light and dark themes for enhanced accessibility. We can either detect the device’s default theme or allow users to set their preferences. Once we know their preference, we can adjust the rest of the app accordingly.

We’ll use the Appearance API to change our app’s theme:

import { useColorScheme } from 'react-native';

const colorScheme = useColorScheme();

const styles = {
 backgroundColor: colorScheme === 'dark' ? '#000' : '#fff'
};

Next, store the theme in state:

const [theme, setTheme] = useState('light');

const styles = {
 backgroundColor: theme === 'dark' ? '#000' : '#fff'
};

// Toggle theme 
toggleTheme = () => {
 theme === 'light' ? setTheme('dark') : setTheme('light');
}

Then, use a theme provider:

const ThemeContext = createContext('light');

function ThemeProvider({ children }) {
 const [theme, setTheme] = useState('light');

 return (
   <ThemeContext.Provider value={{ theme, setTheme }}>
     {children}
   </ThemeContext.Provider>  
 );
}

// Use context
const { theme } = useContext(ThemeContext);
const styles = {
 backgroundColor: theme === 'dark' ? '#000' : '#fff'
};

Define separate style sheets for each theme with the following code:

const lightTheme = {...};
const darkTheme = {...};

const currentTheme = theme === 'dark' ? darkTheme : lightTheme;

<View style={currentTheme.container} />

Best practices for React Native styling

Let’s consider some of the best practices while styling a React Native application.

Organizing styles

We used a theme object that acted as a single source of truth, which is the recommended approach. It allows you to save all the commonly used properties like font sizes, typography, spaces, sizes of components, colors, etc.

This theme can be accessed throughout the entire application using React Context, elimintating the need to update the theme file at every single usage.

Componentize your app

Breaking down the user interface into smaller components helps you make them reusable and more manageable. Always break the screen into smaller components and reuse as much as possible.

This modular approach saves valuable development time and significantly improves the overall codebase’s maintainability. By organizing your app into distinct components, you can quickly locate and update the relevant code whenever there is a change in design specifications or functionality requirements.

Avoid pixel values

Mobile apps are designed to cater to devices with different screen sizes and resolutions. It is crucial to avoid using hardcoded pixel values when defining the layout and styling to ensure that your app provides a seamless user experience across all devices. Instead, it is recommended to adopt a more flexible approach by using flexbox and percentage-based units for styles.

Please note that this is only the case for component layout and not font sizes. Font sizes should use unitless values and the Platform API to adjust font accordingly.

Choose StyleSheet over inline styles

Inline styles not only make components more challenging to read but also hinder maintainability and the reusability of styles. It is recommended to use the StyleSheet object to define styles separately from functional components.

While inline styles can be employed for adding conditional styles, the StyleSheet should be the primary approach.

Conclusion

Styling in React Native can be straightforward if you understand the key differences discussed earlier. We explored building complex layouts using flexbox and percentage-based styles. Additionally, we examined using constants to reuse styles through a common theme object. You can find more information about style props in the React Native documentation.
