so, I know, I know, bootstrap is amazing, bla bla bla.... But you could use bootstrap-sass and then use the mixins to write HTML that doesn't know about bootstrap!

Think about it like this:

1. Bootstrap knows about the HTML
2. The HTML knows about Bootstrap

Now, they are coupled forever :(.

Look into this lovely gist to demonstrate how to break free from coupling your HTML to bootstrap: https://gist.github.com/yury/5662144
