import React, { Component } from 'react';
import {Navbar,Container,Nav,Card,CardDeck,CardGroup} from 'react-bootstrap';


function App() {
  return (
      <CardGroup>
        <Card>
          <Card.Body>
            <Card.Title>Card title</Card.Title>
            <Card.Text>
              This is a wider card with supporting text below as a natural lead-in to
              additional content. This content is a little bit longer.
            </Card.Text>
          </Card.Body>
          <Card.Footer>
            <small className="text-muted">Last updated 3 mins ago</small>
          </Card.Footer>
        </Card>
        <Card>
          <Card.Body>
            <Card.Title>Card title</Card.Title>
            <Card.Text>
              This card has supporting text below as a natural lead-in to additional
              content.{' '}
            </Card.Text>
          </Card.Body>
          <Card.Footer>
            <small className="text-muted">Last updated 3 mins ago</small>
          </Card.Footer>
        </Card>
        <Card>
          <Card.Body>
            <Card.Title>Card title</Card.Title>
            <Card.Text>
              This is a wider card with supporting text below as a natural lead-in to
              additional content. This card has even longer content than the first to
              show that equal height action.
            </Card.Text>
          </Card.Body>
          <Card.Footer>
            <small className="text-muted">Last updated 3 mins ago</small>
          </Card.Footer>
        </Card>
      </CardGroup>
  );
}

export default App;
