In this chapter, we had a look at the widely-used components of Bootstrap that help you design your webpage with relative ease. The simplification of the evolution process of a website, from post-mockup skeleton to fully-fledged web application, has increased significantly over time, mainly due to a modular approach. You can extend or customize the components, and this code reusability is the paradigm of the DRY principle. In the next chapter, we'll take a look at enhancing your Bootstrap experience with JavaScript.
