I created a new Rails 8 app with bootstrap css: rails new my_app -c="bootstrap"

and Bootstrap worked out of the box. It created an application.bootstrap.scss file that included:

@import 'bootstrap/scss/bootstrap';
@import 'bootstrap-icons/font/bootstrap-icons';

I added:

$primary: #792c2c;

$theme-colors: (
  'primary': $primary
);

and it did nothing. I tried stopping the server and running rails assets:precompile but that also did nothing.

• sass
• bootstrap-5
• ruby-on-rails-8

• 2 When you say "I added" where did you add it? I am assuming in the same file (although you didn't specify) but is it before or after you imported bootstrap (it should before). Docs – engineersmnky Commented Feb 3 at 18:08

Add the updated definition before the Bootstrap import:

$primary: #792c2c;

$theme-colors: (
  'primary': $primary
);

@import 'bootstrap/scss/bootstrap';
@import 'bootstrap-icons/font/bootstrap-icons';
