如何在Bootstrap 4 Rails Gem中启用Flexbox

Question

I started a rails project and added bootstrap gem to the Gemfile. Now I want to enable flexbox which according to the bootstrap 4 documentation is done by editing _variable.scss $enable-flex: true .

I added $enable-flex: true in global.scss and added this file to my application.scss . But it's not working.

Answer 1

Add $enable-flex: true; in application.scss before the line with @import "bootstrap";

it works:

application.scss

$enable-flex: true;
// Custom bootstrap variables must be set or imported before bootstrap itself.
@import "bootstrap";

Answer 2

Have a look at this issue.

It mentions the fix to be a simple variable setup in the _bootstrap-flex.scss file

$enable-flex: true;

@import "bootstrap";
