Define a style rule that defines a font-family, font text color, font-size, and background color for the textarea. The style rules can be placed in a style element in the head of the page [or for extra credit] in a separate style sheet. Understand where a style rule is defined (and its syntax) and (optionally) about stylesheets, how a rule is referenced by an element it applies to, how to find out about style properties and allowed values of properties (so you "learn how to learn"), and what happens if there is a syntax error in a rule.
