Bootstrap (currently v3.4.1) has a few easy ways to quickly get started, each one appealing to a different skill level and use case. Read through to see what suits your particular needs.
Flex 工具箱
Bootstrap ported from Less to Sass for easy inclusion in Rails, Compass, or Sass-only projects.
jsDelivr
The folks over at jsDelivr graciously provide CDN support for Bootstrap's CSS and JavaScript. Just use these jsDelivr links.
Install with Composer
You can also install and manage Bootstrap's Less, CSS, JavaScript, and fonts using Composer:
composer require twbs/bootstrapAutoprefixer required for Less/Sass
Bootstrap uses Autoprefixer to deal with CSS vendor prefixes. If you're compiling Bootstrap from its Less/Sass source and not using our Gruntfile, you'll need to integrate Autoprefixer into your build process yourself. If you're using precompiled Bootstrap or using our Gruntfile, you don't need to worry about this because Autoprefixer is already integrated into our Gruntfile.
