In my opinion, this last chapter was awesome! We saw more about Bootstrap customization in terms of both components style and plugin interaction. Bootstrap is a great framework, but what makes it great is the extensibility potential that it has. It matches the perfect world where premade components and customization live in symbiosis.
To finish the book with a flourish, we developed a new Bootstrap plugin, the wrapper for Bootstrap Carousel. The plugin contemplates almost every pattern for the Bootstrap plugin, and it has been very helpful in creating a simple carousel with minimal verbosity.
The plugin is available on GitHub at github.com/silviomoreto/bootstrap-carousel. Take a look at it and create a pull-request! There are a bunch of improvements and new features that could be added to the plugin—perhaps a method to remove slides?
Also, the goal of creating a plugin is to make you able to create a new one in the future or understand a Bootstrap plugin if you need to adjust some part of it. I think you can now see the plugin's code with more familiarity and improve them.
I would like to congratulate you for reaching the end of the book. Understanding a complete framework such as Bootstrap is not a simple task and it is completed by just a small group of developers in the world. Be proud of your achievement.
The understanding of the plugin goes from the basic usage of the scaffolding from the creation of a plugin to the components, elements, and more. All of that was achieved using very useful examples that will be useful some day in your work.
The cherry on top of the pie is that you also learned about Bootstrap 4, which was released recently. This means you are one of the few people who are completely ready to use the new version of the Bootstrap framework.
I hope you liked the journey through the world of Bootstrap and were able to learn a lot from this book. Now it is your turn! You must go and nail every frontend Bootstrap task that you face. I believe that with all the knowledge acquired from the examples covered in this book, you are more than ready to be a true Bootstrap master.
