Bootstrap 3 is here, and it supports mobile design and responsive CSS better than ever. Join author Ray Villalobos for an overview of the new classes, mobile-first approach, and other enhancements in Bootstrap 3, and learn how to migrate your sites and files to the new framework. Find out about the new installation options, updates to grids and scaffolding, and changes to the handling of type, images, and JavaScript. Then learn to integrate the new list group and panel components into your workflow. The course closes with a look at migrating a sample site from Bootstrap 2.3 to 3.0, from replacing template files to tweaking your grid, navigation, and images.
