+    /**
+     * ComputedStyle properties
+     *
+     * Each property stored in ComputedStyle is made up of fields. Fields have
+     * initial value functions, getters and setters. A field is preferably a
+     * basic data type or enum, but can be any type. A set of fields should be
+     * preceded by the property the field is stored for.
+     *
+     * Field method naming should be done like so:
+     *   // name-of-property
+     *   static int initialNameOfProperty();
+     *   int nameOfProperty() const;
+     *   void setNameOfProperty(int);
+     * If the property has multiple fields, add the field name to the end of the
+     * method name.
+     *
+     * Avoid nested types by splitting up fields where possible, e.g.:
+     *  int getBorderTopWidth();
+     *  int getBorderBottomWidth();
+     *  int getBorderLeftWidth();
+     *  int getBorderRightWidth();
+     * is preferable to:
+     *  BorderWidths getBorderWidths();
+     *
+     * Utility functions should go in a separate section at the end of the
+     * class, and be kept to a minimum.
