Lightning Experience / Lightning UI:

A while back salesforce released this very cool next generation user interface called the Lightning Experience. In addition to the entire revamp of the look and feel, this also added additional features like the 'Opportunity Kanban', the 'Assistant' etc.

  • Lightning Experience can be turned ON at the profile level, or for individual users using permission sets.
  • ALL standard profiles are lightning UI enabled by default, when you enable Lightning UI for your organization. [Workaround: Replace standard profiles with custom profiles]
  • Visualforce pages work as usual in the lightning UI, however you might want to do a sanity check to make sure nothing is broken.
  • Visualforce pages open with the old look and feel. The old look and feel is referred to as Salesforce Classic.

Lightning Design System:

  • Lightning Design system could be though of as an equivalent to 'Twitter Bootstrap'.

  • The design system comes with pre-built components such as pop-up modals, tree structure, buttons etc.
