In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "We can select HTML elements through the use of the d3.select function."

A block of code is set as follows:

class Animal
{
public:
virtual void Speak(void) const //virtual in the base class
{
  //Using the Mach 5 console print
  M5DEBUG_PRINT("...
");
}

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Clicking the Next button moves you to the next screen."
