I’ve worked with Bootstrap a lot since the 2013 release of Bootstrap 3.0. I’ve contributed to the Bootstrap docs, and rank first for Bootstrap on Stack Overflow. I feel more than prepared to tell you everything you need to know about it. With this article, I hope to demystify Bootstrap in a clear and understandable way.

BUT First, let’s talk about you. I hope that if you’re reading this you have a good understanding of HTML and CSS. If you haven’t built any Websites, don’t know what CSS Specificity is, or don’t know the difference between using #abc and .abc in CSS, this is NOT the article for you. Instead you should learn the basics of HTML and CSS.
