A block of code is set as follows:

Any command-line input or output is written as follows:
There once was a citizen in the town of Narnia, whose name was Malena. Malena loved to hang with their trusty dog, King Kong. You could always see them strolling through the market in the morning, wearing their favorite blue attire.
Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "As you can see from the preceding screenshot, the deaths column continues to rise, as does the number of cases, which we will take a look at a little later in this problem."
