Disclosed are examples of systems, apparatus, methods and computer program products for causing re-sizing of items in a user interface of a web browser-based application. A bounding window of a web browser comprising a presentation of items can be caused to be displayed in a user interface on a display of a device. First keyboard input from a user interacting with a first item can be processed. A first edge of a first item can be caused to be transformed to a re-configurable state. Second keyboard input from the user interacting with the first item can be processed. A size of the first item can be caused to be changed by causing the first edge to move from a first relative position to a second relative position with respect to the other items displayed in the user interface.
