Abstract: Various techniques for dynamic localization of a client device are disclosed. In an example embodiment, a geographic location associated with a client device is determined, along with a localized language requirement associated with a geographic location. When content is received at the client device for presentation on a display, a set of definitions defining elements of a user interface are accessed. The definitions are used to resize elements to be displayed based on the content and the localized language requirement. Various additional embodiments access definitions and manage the dynamic localization in different ways.
