I don't use Bootstrap, but 1 thing made me use it. The class collapse with certain button. I have got more than 2 thousand line of CSS and when I linked and imported BOOTSTRAP, it started remaking all my styles. In another word, Bootstrap styles and My Own CSS styles are collapsing and making unusable and ugly UI.
The question is: Can I include only style classes that I really need?
Googled :D I have no XP in this situation...
Within the bootstrap documentation I have found that you can download the styles separately, selecting which ones you need
