   Normalize.css is a customisable CSS file that makes browsers render all
   elements more consistently and in line with modern standards. We researched
   the differences between default browser styles in order to precisely target
   only the styles that need normalizing.

   How comment documentation is written:
   Comments: (anchor) (type of change) (summary of issue) in (affected browsers)
