In this chapter, we understood Bootstrap's Grid System and created two different types of projects: a static demo webpage and an online shopping Rails app. We saw how to use the Grid system, and make our homepage responsive to various sizes of devices. There are still many pages left unstyled in the current app: add product page, edit product page, and single product page. We will use Bootstrap to style them in subsequent chapters.

In the next chapter, we will understand various typography support from Bootstrap, play with beautiful Bootstrap buttons, and do more with images using Bootstrap.
