   7 // All buttons start with mw-ui-button class, modified by other classes.
   8 // It can be any element.  Due to a lack of a CSS reset, the exact styling of
   9 // the button depends on what type of element is used.
  10 // There are two kinds of buttons, the default is a "Call to Action" with an obvious border
  11 // and there is a quiet kind without a border.
  12 //
  13 // Styleguide 2.
  14
  15 // Neutral button styling
  16 //
  17 // These are the main actions on the page/workflow. The page should have only one of progressive and destructive buttons, the rest being quiet.
