Example 2: css padding vs margin

/* Answer to: "css padding vs margin" */

/*
  Margin is outer space of an element, while padding is inner space
  of an element. Margin is the space outside the border of an
  element, while padding is the space inside the border of it.
  Margin accepts the value of auto: margin: auto , but you can't
  set padding to auto.
