Where to Get Bootstrap 4?

There are two ways to start using Bootstrap 4 on your own web site.

You can:

• Include Bootstrap 4 from a CDN
• Download Bootstrap 4 from getbootstrap.com

One advantage of using the Bootstrap 4 CDN:
Many users already have downloaded Bootstrap 4 from MaxCDN when visiting another site. As a result, it will be loaded from cache when they visit your site, which leads to faster loading time. Also, most CDN's will make sure that once a user requests a file from it, it will be served from the server closest to them, which also leads to faster loading time.

jQuery and Popper?
Bootstrap 4 uses jQuery and Popper.js for JavaScript components (like modals, tooltips, popovers, etc). However, if you just use the CSS part of Bootstrap, you don't need them.
