Bootstrap is an open source toolkit for developing with HTML, CSS, and JS. Quickly prototype your ideas or build your entire app with our Sass variables and mixins, responsive grid system, extensive prebuilt components, and powerful plugins built on jQuery.
npm install bootstrap
gem install bootstrap -v 4.1.0
When you only need to include Bootstrap's compiled CSS or JS, you can use BootstrapCDN.

Bootstrap supports the latest, stable releases of all major browsers and platforms. On Windows, we support Internet Explorer 10-11 / Microsoft Edge.
Alternative browsers which use the latest version of WebKit, Blink, or Gecko, whether directly or via the platform’s web view API, are not explicitly supported. However, Bootstrap should (in most cases) display and function correctly in these browsers as well. More specific support information is provided below.
