Setting a Div's height to cover the entire screen in React
To set the height of a Div in React to cover the entire screen, set its height to 100vh, for example <div style={{height: '100vh'}}>...</div>. When the element's height is set to 100vh, it covers 100% of the viewport height.
const App = () => {
return (
<div style={{height: '100vh'}}>
<h2>hello world</h2>
</div>
);
};
export default App;
divWe set the height of the to be 100% of the viewport height using the vh unit .
If we need to set the height of the root in our React application div, we can do it in the App.css file or in the index.css .
#root {
height: 100vh;
}
Here is how you import the App.css file to make the styles take effect.
// 👇️ import your css file
import './App.css';
const App = () => {
return (
<div>
<h2>hello world</h2>
</div>
);
};
export default App;
The examples above assume that the root div element in the public/index.html file has an id of root.
We should make sure that the roots are positioned correctly div.
When importing global CSS files in React, the best practice is to import the CSS file into
index.jsa .js file.
The index.js file is the entry point of your React application, so it will always run.
On the other hand, if we import a CSS file into a component, the CSS styles may be removed once our component unmounts.
