npm i bootstrap

Step 2: Create your custom scss file and write the variable you want to override. Then include the bootstrap scss file using import.

$SASS_variable: values;
@import "node_modules/bootstrap/scss/bootstrap"

Step 3: Convert the file to CSS using live server extension.

Step 4: Include the converted scss file to your HTML after the link tag of Bootstrap CSS
