title: where to set default font size of entire web site, Jekyll, bootstrap 3
body: <p>I'm using Jekyll and Bootstrap-3 style and would like to increase the default font size for 14px to about 20px if possible for the entire web site.  I found a setting for something called "body" in the page source code.  It appears to be set in a file called
  /project/assets/bootstrap-3/bootstrap/css/bootstrap.min.css.  I'm speculating that I could make changes in there but have seen it suggested not to edit this file.  Is there an easy way to create a new .css file, that will be called by jekyll that will set the default font size to 20px?</p>
