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