In this chapter, you built a navigation menu with Less. The navigation contains, amongst other things, hovers, contrast colors, and icons that can all be set with a few basic settings. You have learned how to use nesting rules, mixins, and built-in functions in Less. At the end of the chapter, you have understood and used complex Less code. All this newly acquired knowledge will be very useful in the next chapter. In the next chapter, you will learn how to find and build reusable Less code. This will help you work faster and obtain better results.
