Methods, systems, and computer-readable media for enhanced layout editing of one or more child objects within a container displayed by a computer system are disclosed. Editing first involves detecting a layout edit operation for a child object displayed on a video display of a computer system. A request is then sent via an application program interface provided by an abstraction layer to initiate editing of the object layout by the abstraction layer. The abstraction layer receives the edit operation request and determines the layout limitations and type of parent object or container in which the child object is displayed based on properties related to the child object to be edited. The abstraction layer reads a set of properties related to the object and the container in which the object is displayed. The abstraction layer then edits the layout of the child object based the properties of child and the parent container by modifying one or more of the properties of the child object or the parent container in accordance with constraints either associated with the child object or its parent container, or both, and includes accommodation for modifications in accordance with one or more functional relationships defined between the parent and child.
