If I could give this course AND instructor 20 stars I would! This course is thorough in explaining the elements of bootstrap.I love that before you start coding projects he walks you through EACH bootstrap feature and you create your own sandbox of the features to come back to if you forget what they do. The websites he builds during the class are also great and can even be used , if you know the backend and JS.
If you are looking to learn bootstrap-TAKE THIS COURSE!!!
