Summary
In this chapter, we have covered all components in Bootstrap that rely on JavaScript. This included: Modals, Tooltips, Popovers, Collapse, and Carousel.
In the next chapter, we will see how in Bootstrap 4 the framework has moved from Less to Sass as its CSS preprocessor. We will cover the basics of using Sass in a Bootstrap theme. I'll also explain how you can customize or use existing variables, or write your own.
