How do I make a Container fill the whole page in React?-CodePudding

I am trying to get my container from react-bootstrap to fill the whole page both height-wise and width-wise. This is my CSS for my App.js:

.main-content{
  display: flex;
  height: 100vh;
  width: 100%;
  background-color: black;
  color:white;
}

and here is the code inside my App.js:

import React, { useState, useEffect} from 'react';
import { Container } from 'react-bootstrap';
import 'bootstrap/dist/css/bootstrap.min.css';
import './App.css';

const App = () => {
  return (
    <Container className='main-content'>
      Hello World
    </Container>
  )
}

export default App

And when I load the webpage the page is filled height-wise but has some spaces in the width on the left and right:

CodePudding user response：

You can always set the width to 100vw. Your component probably has a parent that doesn't fill the page.

CodePudding user response：

Don't put it inside <Container>. Bootstrap's container has max-width or width and margin-left: auto; margin-right: auto applied to it.

So, it does not fill page and is center aligned.

Do something like this:

<div className='main-content'>
  <Container>
    Hello World
  </Container>
</div>
