Answer

To reduce your Bootstrap bundle size, you can import only the specific components and utilities you need. This approach involves using Bootstrap's source files and customizing your build process.

<!-- BEGIN COPY / PASTE -->
        // Import only the necessary components and utilities
        @import "bootstrap/scss/functions";
        @import "bootstrap/scss/variables";
        @import "bootstrap/scss/mixins";

        // Import specific components
        @import "bootstrap/scss/buttons";
        @import "bootstrap/scss/card";

        // Import specific utilities
        @import "bootstrap/scss/utilities/api";
        <!-- END COPY / PASTE -->

Additional Comment:

Ensure you have Bootstrap's source files available in your project, typically through npm or yarn.
Create a custom SCSS file where you import only the components and utilities you need.
Compile your custom SCSS file using a tool like Sass to generate a minimized CSS file.
Include the generated CSS file in your project to reduce the overall bundle size.
