如何将 Bootstrap 3 降级为 2
How to downgrade Bootstrap 3 to 2
我正在使用 Bootstrap 3.3.2，但它不能 运行 在 IE7,8 上正常运行，所以我需要将它降级到版本 2。我该怎么做？
非常感谢。
好吧，去下载版本 2 的必要文件（使用 http://getbootstrap.com/2.3.2/ is likely going to be quite helpful) and set your site up to use those in place of the 3.x assets. This is a major-version change, so there's going to be breaking functionality all over the place. Things changed a lot from 2.x to 3.x, so you're going to have to make a lot of syntactic changes in your code to match the 2.x docs. There isn't a "downgrading" guide published, but the log at https://github.com/twbs/bootstrap/releases 可能对你有帮助。
根据 Techrepublic 的这篇文章，这似乎是不可能的：http://www.techrepublic.com/blog/software-engineer/bootstrap-3-says-mobile-first-everything-else-later/
不向后兼容
The reason the latest version is not backward compatible is a number
of class changes. The most notable changes include the removal of the
fluid classes (.container-fluid and .row-fluid) that were used to
build responsive interfaces. With Bootstrap 3.0.0, sites are
responsive by default, but there is an option to disable that feature.
Gone are the days of pixel width pages -- say hello to
percentage-based layouts going forward. Other changes that caused
problems include the removal of search form controls (.form-actions
and .form-search) and the .navbar-inner class.
There are too many class changes to cover here, but the online
documentation provides all the necessary details as well as 3.0.0
equivalent features (where available). In addition, the official
Bootstrap blog post announcing the new version contains useful
information.
