Bootstrap's Default Settings
Bootstrap's global default font-size is 14px, with a line-height of 1.428.
This is applied to the
<body> element and all paragraphs (<p>).
In addition, all
<p> elements have a bottom margin that equals half their computed line-height (10px by default).Bootstrap vs. Browser Defaults
