Get started by including Bootstrap’s production-ready CSS and JavaScript via CDN without the need for any build steps. See it in practice with this Bootstrap CodePen demo.:
Include Bootstrap’s CSS and JS. Place the tag in the < head > for our CSS, and the < script > tag for our JavaScript bundle (including Popper for positioning dropdowns, poppers, and tooltips) before the closing . Learn more about our CDN links.
You can also include Popper and our JS separately. If you don’t plan to use dropdowns, popovers, or tooltips, save some kilobytes by not including Popper.
