Updated CSS Nesting Syntax to Avoid Common Copy-and-Paste Errors

looks like css nesting is really coming! "Chromium as of 109.0.5394.0 is updated with the new syntax."[0]

the syntax has been finalized to allow an implied "&" so that it matches scss more closely than the initially selected syntax, to avoid copy-and-paste errors when moving from scss to plain css with nesting.
