An example of the use of escape codes and quoting is found next. (X)HTML automatically
―collapses‖ multiple whitespace characters down to one whitespace. So, for example, including
multiple consecutive tabs in your HTML shows up as only one space character.
In this example, the tag is used to tell the browser that the text is preformatted and
that it should not collapse the whitespaces inside of it. Using allows the tabs in the
example to be displayed correctly in the output. The result can be seen in Figure 3-1.
