How do style the console output using CSS?

You can add CSS styling to the console output using the CSS format content specifier %c. The console string message can be appended after the specifier and CSS style in another argument. Let's print the red color text using console.log and CSS specifier as below,

console.log("%cThis is a red text", "color:red");

It is also possible to add more styles for the content. For example, the font-size can be modified for the above text

console.log(
"%cThis is a red text with bigger font",
"color:red; font-size:20px"
);
