Limit the number of properties in a rule set.

Specifying a large number of properties in a rule set is usually an opportunity to break down the rule set into smaller more reusable components. It is also a sign that you might not be leveraging the true power of the "cascade", as you are explicitly defining a large number of properties many times.

Bad: large number of properties

.class {
  color: #f00;
  font: 15px arial, sans-serif;
  margin: 0;
  padding: 0;
}

Good: small number of properties

.class {
  margin: 0;
  padding: 0;
}

You can specify that the count of properties include properties in nested rule sets via the include_nested option. This is useful if you care about the overall complexity of a generated rule set, rather than just each individual set.
