import React from 'react';
import { Alert } from 'reactstrap';
const Example = (props) => {
  return (
      <Alert color="success">
        <h4 className="alert-heading">Well done!</h4>
        <p>
          Aww yeah, you successfully read this important alert message. This example text is going
          to run a bit longer so that you can see how spacing within an alert works with this kind
          of content.
        </p>
        <hr />
        <p className="mb-0">
          Whenever you need to, be sure to use margin utilities to keep things nice and tidy.
        </p>
    </div>

Dismissing

For the most basic use-case an uncontrolled component can provide the functionality wanted without the need to manage/control the state of the component. UncontrolledAlert does not require isOpen nor toggle props to work.

import React from 'react';
import { UncontrolledAlert } from 'reactstrap';
function AlertExample() {
  return (
    <UncontrolledAlert color="info">
      I am an alert and I can be dismissed!
    </UncontrolledAlert>
  );
}
export default AlertExample;
