Step 4

Let's improve the styling; update the Note.js file as follows.

  1. Import the following Material-UI components
import Box from "@material-ui/core/Box";
import Paper from "@material-ui/core/Paper";
  1. Update where the note.text is displayed!
<List component="div" disablePadding>
  <ListItemText
    secondary={
+     <Box mx={4}>
+       <Paper elevation={4}>
+         <Box p={4}>
            <ReactMarkdown
              children={note.text}
              remarkPlugins={[remarkGfm]}
            />
+         </Box>
+       </Paper>
+     </Box>
    }
  />
</List>

Save the files and revisit the app.

Notice that the Material-UI Box component is a wrapper for most CSS utility needs. For example, I primarily used it to incorporate Material-UI spacing system, a set of shorthand responsive margins, and padding utility classes to modify an element's appearance.
