  <title>CSS Values Test: computed value of 3 calc() values</title>


  <!--
  "
  Where percentages are not resolved at computed-value time,
  they are not resolved in math functions, e.g.
  'calc(100% - 100% + 1px)' resolves to 'calc(0% + 1px)', not to
  '1px'. If there are special rules for computing percentages
  in a value (e.g. the 'height' property), they apply whenever
  a math function contains percentages.
