making antd modal full screen without any padding or margins

Question

I'm new to programming. Here I have an antd modal and I've been trying to find a way to make it full screen. I want the modal to be full scree when it's opened and it shouldn't have any margin or paddings. For example, in the code I added width={1000} but there is still some margin on the left and right of the modal.

So how do I make the modal to take the whole screen without any margin and padding?

1. Remove the fixed value for modal width and the centered attribute from your code file:

index.js

import React, { useState } from 'react';
import ReactDOM from 'react-dom';
import 'antd/dist/antd.css';
import './index.css';
import { Modal, Button } from 'antd';

const App = () => {
  const [visible, setVisible] = useState(false);
  return (
    <>
      <Button type="primary" onClick={() => setVisible(true)}>
        Open Modal of 1000px width
      </Button>
      <Modal
        title="Modal 1000px width"
        // This was removed
        // centered
        visible={visible}
        onOk={() => setVisible(false)}
        onCancel={() => setVisible(false)}
        // This was removed
        // width={'1000'}
      >
        <p>some contents...</p>
        <p>some contents...</p>
        <p>some contents...</p>
      </Modal>
    </>
  );
};

ReactDOM.render(<App />, document.getElementById('container'));

2. You need to add these CSS rules to the CSS file.

index.css

.ant-modal, .ant-modal-content {
 height: 100vh;
 width: 100vw;
 margin: 0;
 top: 0;
}
.ant-modal-body {
 height: calc(100vh - 110px);
}
