I love Twitter Bootstrap 2.0 - I love how it\'s such a complete library... but I want to make a global modification for a very boxy-not-round site, which is to get rid of al
This question is pretty old however it is highly visible on search engines even in Bootstrap 4 related searches. I think it worths to add an answer for disabling the rounded corners, BS4 way.
In the _variables.scss there are several global modifiers exists to quickly change the stuff such as enabling or disabling flex gird system, rounded corners, gradients etc. :
$enable-flex: false !default;
$enable-rounded: true !default; // <-- This one
$enable-shadows: false !default;
$enable-gradients: false !default;
$enable-transitions: false !default;
Rounded corners are enabled by default.
If you prefer compiling the Bootstrap 4 using Sass and your very own _custom.scss like me (or using official customizer), overriding the related variable is enough:
$enable-rounded : false
