Several items are presented in a monospace font, which can be plain or italic. Here’s
what each one means:
■ plain mono—Applied to commands, filenames, file extensions, directory names,
and HTML input. For example, HTML tags such as <table> and <p> appear in
this font.
■ mono italic—Applied to placeholders. A placeholder is a generic item that
replaces something specific as part of a command or computer output. For
instance, the term represented by filename would be the real name of the file, such
as myfile.txt.Workshop
In the “Workshop” section, you can reinforce your knowledge of the concepts in the les-
son by answering quiz questions or working on exercises. The Q&A provides additional
information that didn’t fit in neatly elsewhere in the lesson.
