Abstract:

Systems and methods for modifying an appearance of a control based on detected changes in underlying content are disclosed. An example method includes: displaying a user interface on the display, the user interface including first content that is displayed at a respective region of the display using a first content-display value for a content-display property. The method also includes: displaying a control overlaying the first content, and the control having an appearance determined based on the first content-display value. The method additionally includes: detecting a change at the respective region that causes second content to be displayed at the respective region using a second content-display value for the content-display property. In response to detecting the change, the method includes: determining an updated appearance for the control based on the second content-display value for the content-display property; and displaying the control with the updated appearance overlaying the second content.
