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.
