css - How to change Bootstrap's global default font size?

Question

Bootstrap's global default font-size is 14px, with a line-height of 1.428. How can I change its default global settings?

Will I have to change bootstrap.min.css in all the multiple entries?

Answer 1

Bootstrap uses the variable:

$font-size-base: 1rem; // Assumes the browser default, typically 16px

I don't recommend mucking with this, but you can. Best practice is to override the browser default base font size with:

html {
  font-size: 14px;
}

Bootstrap will then take that value and use it via rems to set values for all kinds of things.
