 More Efficient? When writing code: DRY

    Don’t Repeat Yourself! Reduces HTTP requests with multiple stylesheets @import Helps you write more advanced code faster Cleaner, easier to read once you are familiar Using variables, make site-wide changes in fewer places Different output styles can be chosen depending on goals
