Bootstrap 3 and Shiny
Since the first edition of this book, Shiny has migrated from Bootstrap 2 to Bootstrap 3. There are now many functions, both within Shiny and in packages (such as shinyBS and shinythemes, both available on CRAN), which enhance the way you can style your applications straight from Shiny. There is more on advanced layout functions, Bootstrap 3, and packages to help you to style your applications in Chapter 5, Advanced Applications I – Dashboards.
