Is there a way for me to position my button above the text?

I am trying to align my text and button at the top of the screen, but there seems to be a gap between the two elements. I attempted to add marginBottom to the text, which helped move it to the top. However, when I added marginBottom to the button as well, it did not align with the top as desired.

How can I resolve this positioning issue? What mistake am I making in my styling? Please provide an explanation.

import { StyleSheet, Text, View, Button } from 'react-native';

export default function App() {
  return (
    <View style={styles.container}>
      <Text style={{ margin: 16, marginBottom: '80%', backgroundColor: 'black' }}>Hello World</Text>
      <View style={{ marginBottom: '80%' }}>
        <Button title='Click me' />
      </View>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

Answer №1

You have utilized the CSS properties alignItems: 'center' and justifyContent: 'center'. When combined, these two properties center the contents of the container. alignItems:center vertically centers the contents, while justifyContent:center horizontally centers them.

As the Text element is above the View containing the Button, applying a marginBottom to the Text will create space between them. You can see the button slightly shifting downwards when the marginBottom is added to the Text.

In essence, your code is functioning as instructed: the container is attempting to center all of its children.

To rectify this, consider removing the

container:{ alignItems:'center', }
property. This action will likely move all your elements to the top of the container. Following that adjustment, you can add a marginTop to the Text element to push the contents downwards.

Answer №2

Modify the marginBottom values from %80 to "auto".

  return (
    <View style={styles.container}>
      <Text
        style={{ margin: 16, marginBottom: "auto", backgroundColor: "white" }}
      >
        Hello World
      </Text>
      <View style={{ marginBottom: "auto" }}>
        <Button title="Click me" />
      </View>
    </View>
  );
