Styles are cascading, meaning that you can refine a rule already defined, by overloading a style or adapt it to a context.
For example, if you define a style for the <a> tag, you can change the definition when this tag is contained in a table with the "<table> <a>" rule .
The order of statements is important. A new rule in a single file or afteran imported file, supersedes the previous one for each property defined in the new rule.

List of statements which each associates a value to a property:
font-style:100%;
color: black; Font stack

font-family: { Helvetica, Arial, sans } Measure

The space between lines may be defined also by the line-height property.
