Overview

Represents a @page’s margin box declaration. A page margin box consists of a margin symbol, like ‘@top-left-corner` and a list of declarations.

MarginBox inherits from the Selector class, since there are inevitable similarities. The specified margin symbol can be reached by the ‘value` property of the instance of this class.

Instance Method Details

#add_property(prop, deep_copy = false) ⇒ Object

Looks for a ‘size` property to delete the values that should be ignored according to the @page W3 specification.

If a size property declaration is qualified by a ‘width’, ‘height’, ‘device-width’, ‘device-height’, ‘aspect-ratio’, ‘device-aspect-ratio’ or ‘orientation’ media query (or other conditional on the size of the paper), then the declaration must be ignored.
