A computer-implemented method and corresponding systems and apparatuses for configuring the visual appearance of a webpage. The method involves providing access to color schemes through a user interface of a software application and assigning user selected color schemes to corresponding sections of the webpage. Each color scheme includes at least one foreground color paired with a corresponding background color that contrasts the foreground color. Color schemes can include user-configured color schemes and system-generated color schemes. The method further involves generating source code representing the webpage. The source code includes scoped containers, where the scope of a container includes an assigned color scheme applied to one or more elements within a section that the container represents. Color schemes can be applied using Cascading Style Sheets (CSS) custom properties. Containers can be nested so that child containers inherit and/or override colors specified in the color schemes of their parent containers.
