  ║  CSS rules look like this:                                       ║
  ║    .class-name {                                                 ║
  ║      property: value;                                            ║

  ║  The .class-name selects an element from the HTML.             ║
  ║  The properties change how it looks.                            ║
  ║                                                                  ║
