“The idea of adjustable site options to support user preferences and personalized accessibility has a long history and several mature manifestations, such as the Fluid Project’s User Interface Options. However, current solutions can be heavyweight in terms of their dependencies and setup, requiring the adoption of particular frameworks or libraries.
