In this chapter, you will study Less in more detail, where you will learn more about variables and mixins. Variables in Less can be reused anywhere in the code. Although they are often defined in a single place, they can also be overwritten elsewhere in the code. They are used to define commonly used values that can be edited only once at a single place. Based on the Don't Repeat Yourself (DRY) principle, commonly used values will help you build websites that are easier to maintain. Mixins are used to set the properties of a class. They bundle tasks in a single line of code and are also reusable. You will learn how to create, use, and reuse them in your project and write better CSS without code duplications.
This chapter will cover the following topics:
Commenting on your code
Using variables
Escaping values
Using mixins
