"Mobile-first" Bootstrap 3 is almost ready
Mobile use cases are the major focus for the next version of the open source web frontend framework Bootstrap. Under the heading of "Bootstrap 3 will be mobile-first", the developers have merged the responsive CSS templates into the core bootstrap.css file, dropping support for Internet Explorer 7 and Firefox 3.6 in the process. The changes are aimed at making site designs implemented in Bootstrap adaptable to mobile resolutions by default, without the user having to explicitly enable additional functionality. Bootstrap, which originated at Twitter, has become popular with many developers and is used by hundreds of sites.
Judging by the pull request on GitHub that the developers are using to track the progress of their development, Bootstrap 3 is close to be completed and the developers say they are "almost ready to do an official release candidate". Interested users who want to test the new "mobile-first" code can do so by downloading the work in progress code from GitHub. The most recent stable release of Bootstrap is version 2.3.2 from 17 May.
