This site is using jekyll and Bootstrap with Sass.
Bootstrap is installed from the source files and the scss directory copied to _sass/css/bootstrap of the site.
BootstrapCDN is also used to deliver cached version of Bootstrap’s compiled CSS and JS with CDN versions of jQuery and Popper.js.
To test the site locally:
From the root of project run the commands:
make build
make serve
The site is using a Gemfile, so command like jekyll serve with bundle exec prefixed is appropriate:
bundle exec jekyll build
bundle exec jekyll serve
