Well, that does it for my "Bootstrap Primer". I know it's a ton of info to digest in a short amount of time. I learned Bootstrap in a "trial by fire" method - forced myself into it while tossing aside my preconceived notion that frameworks were all junk for lazy programmers....because I was way wrong.
Using Bootstrap will standardize our development so that most of our apps and sites will look like a unified family for the first time in history. Using Bootstrap will allow us to create mobile-friendly apps, maintain less complicated code, and allow us to focus on the user experience instead of spending days coding the minutia for something that already exists in the framework.
Please let me know if you have questions about these lessons. I highly recommend using the code examples herein and creating them into snippets in your code editor. I use them every day.
