Question regarding $font-size-base

[myplaneticket]

Sorry to post this here, but who better to ask then the creators of BS4 :)

I couldn't find a reliable answer in the docs and was hoping to get some insight here to remove all doubts.

Should the font size for BS4 elements be changed from the root element only?

For example:

html { font-size: 14px }

Is it okay for me to change / override variables (using _custom.scss) in order to alter bootstrap's font size? Or should I not be doing it this way?

For example:

html { font-size: 16px }

// Changing bootstrap variable to 
$font-size-base:             	    0.8125rem; //instead of 1rem
$font-size-lg:                      1.25rem;  
$font-size-sm:   		    0.75rem;  

$h1-font-size: 			    1.5rem;   
$h2-font-size: 			    1.375rem; 
$h3-font-size: 			    1.1875rem;
$h4-font-size: 			    1.0625rem;
$h5-font-size: 		            0.9375rem;
$h6-font-size: 			    0.875rem;

$display1-size:                     5rem !default;
$display2-size:                     4.5rem !default;
$display3-size:                     3.5rem !default;
$display4-size:                     2.5rem !default;

Hey @myorangeca, we've changed font size to be relative to $font-size-base here:
#24060

I'd say change $font-size-base and not the root size
