Bootstrap 4 is a significant change from its earlier versions. Following are some of the necessary changes:
  • CSS is moved from LESS model to SASS model.
  • Print pages: Support for printing pages ensures that the size of the printed page is good enough on larger screens. This is done using flex and new print styles.
  • By adding uniform code for custom and regular checkbox and radio buttons, form validations are now much more accessible.
  • For JS behaviors “data” attribute is used and for group toggling “btn-group-toggle” is added newly.
  • Table classes are now named “dark-*” instead of “inverse.”
