With Alexa Presentation Language (APL), you can build Alexa skills with voice and visual experiences that apply conditional layouts and data binding. If you have developed skills for Alexa-enabled devices with a screen, then you are familiar with display templates. You can use APL to create the equivalent of display templates.
