How to read this

  • An inherited property only needs writing once on the parent — every child picks it up. Most text properties work this way.
  • A shorthand resets whatever you leave out. Writing background: red alone also wipes a background image you set earlier.
  • When rules collide, the more specific selector wins; only when specificity ties does source order decide.
  • Animate transform and opacity for smoothness. Changing width or top forces the layout to be recalculated.
