React

You can write JSX and use React components within your Markdown thanks to MDX.

export const Highlight = ({children, color}) => ( <span style={{
      backgroundColor: color,
      borderRadius: '2px',
      color: '#fff',
      padding: '0.2rem',
    }}>{children}</span> );

Docusaurus green and Facebook blue are my favorite colors.

I can write Markdown alongside my JSX!
