• Element selectors keep styles as global as possible

• ID selectors identify things (one per page)

  .layout { […] }
  [data-layout="bartok"] { […] }

• 24:25 - "The most common product mistake is rushing." (more and more stuff)

• Loops are better than individual controls

• The iphone is a consumer machine, not productivity
