## Notes


Margins cannot be less than 1 pixel or so large that the text cannot be displayed. If marginHeight is specified but marginWidth is not, marginWidth is set to 0. If the document hosted in the frame or iframe has margin-top or margin-bottom properties set either through Cascading Style Sheets (CSS) or through the topMargin or bottomMargin properties of the body element, then this property is ignored.
