Bootstrap 4.1 Released

Bootstrap 4.1 Released

This week the Bootstrap team released the first minor version of Bootstrap 4, version 4.1! On the heels of ten new Bootstrap themes that shipped last month, the next version has some new utility classes, fixes, and documentation updates.

New Utility Classes

It was hard not to notice the number of new utility classes that shipped in Bootstrap 4.1. Here’s a list of the highlighted utility classes in Bootstrap 4.1:

  • .flex-fill, .flex-grow-*, and .flex-shrink-* utilities
  • .text-monospace utility
  • .text-body (default body color), .text-black-50 (50% opacity black), and .text-white-50 (50% opacity white) utilities
  • .shadow-* utility for adding box shadows
  • Responsive utilities .w-auto and .h-auto

Bootstrap 4 Themes

The themes are built with Bootstrap 4, and sellers go through an application process to become eligible to sell themes. Some of the themes are built by the Bootstrap team, and I’d bet that buying a theme for educational purposes could be a great way to see how experienced Bootstrap developers build themes with Bootstrap.
