[React] Extend styles with styled-components in React

In this lesson, you will learn how to extend styles from one styled-component to another in a React app. This is helpful when you have two styled-components that are similar but differ in one or more CSs properties.

 

import styled from 'styled-components';

export const Button = styled.button`
  background-color: #FF851B;
  border-radius: 5px;
  color: white;
  display: block;
  font-weight: bold;
  font-size: 22px;
  padding: 16px 32px;
  text-transform: uppercase;
  margin: 100px auto;
`;

export const HelpButton = styled(Button)`
  background-color: #FF4136;
  margin: 15px;
  position: fixed;
  bottom: 0;
  right: 0;
`;
