Building unique CSS classes with Material UI v5 theme - A step-by-step guide

Incorporating Material UI v5 into my application has been a smooth process, except when it comes to using react-d3-tree for rendering SVG tree charts. This library allows for custom CSS class names to be added to the <path> elements that connect the tree nodes. I am eager to pass these custom class names to react-d3-tree while also utilizing MUI's theme variables. Importing a simple .css file will not suffice for this task.

My question is: How can I create and use statically named custom CSS classes in conjunction with MUI v5, ensuring they align with the defined MUI theme that styles other components within my app?

To create a reusable CSS class locally, you can define the class within the sx property of a parent component. Here's an example:

function Child({ message, className }) {
  return <Typography className={className}>{message}</Typography>;
}

function Parent() {
  return (
    <Box
      sx={{
        '.childClass': {
          color: 'primary.main'
        }
      }}
    >
      <Child message="Child with no css class defined" />

      <Child className="childClass" message="Child with css class defined" />
    </Box>
  );
}

In this scenario, the value 'primary.main' corresponds to theme.palette.primary.main, as explained here.
