Styling is a crucial aspect of web development that ensures your applications are visually appealing and user-friendly. React offers several approaches to styling components, from traditional CSS and Sass to modern CSS-in-JS solutions like Styled-Components.

              <h1 className="title">Hello, World!</h1>
          </div>
      );

          </div>
      );
  }

          secondary: 'darkblue'
      },
      spacing: {
          padding: '20px'
      }
  };

  function App() {
      return (
          <ThemeProvider theme={theme}>
              <Container>
                  <Title>Hello, World!</Title>
              </Container>
          </ThemeProvider>
      );
  }

Using Theme Values:
