title: Bootstrap reduce font size
body: <p>I want to use some of the Bootstrap's components (dropdown button). So I implemented dropdown css and js files and change <code>html{font-size:62.5%}</code> to <code>100%</code> both in .css and .min.css files, but this change does not applied. When I wanted to overwrite it with my own css file, it also does not applied. How can I make the font size 100%, or disable bootstrap typography and only use some of components?
  Thanks for answer.</p>
