We provide compiled CSS and JS (bootstrap.), as well as compiled and minified CSS and JS (bootstrap.min.). Source maps (bootstrap..map) are available for use with certain browsers' developer tools. Bundled JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) include Floating UI and Vanilla Calendar Pro. All CSS files work for both LTR and RTL layouts thanks to logical properties—simply set dir="rtl" on your HTML element.
