User interface design practices in simple single page web applications

The single page Web design is an extreme approach of designing the Web applications. It limits the structure of the application to fit into only one single physical Web page and suppresses the further navigational capabilities. Such limitations strongly affect the design process of the application development, putting more emphasis on the design of the user interface components. We present and discuss the list of five higher level user interface design principles with implementation examples that make the development process easier and bring additional application usability.
