Summary
If you've made it this far, you have everything you need ready to do some serious work. You have learned the basics of a new Bootstrap 4 project. You can easily set up a new project with Bootstrap CLI now and build a responsive navbar (navigation). The navbar uses the JavaScript Collapse plugin. You understand how to compile Bootstrap's Sass code into CSS now and finally got a better understanding of Bootstrap CSS and HTML code, including browser support.
Note
This may be a good point to save a copy of these files so that they're ready for other future projects.
In the next chapter, you will learn how to set up your own build process with Gulp and automatically compile your projects.
