In this long but useful chapter we learnt what preprocessors are, the differences between the two most popular ones – and we learned how to use Sass, through its:
Lighten and darken properties
And we used Sass to configure our breakpoints and text elements through them, making it easier to write and maintain your CSS.
In the next chapters we will do a recap of what we learnt 'til now – and we'll also explore the future of type on the web.
I bet you had a ton of fun!
