What type of programming is Stacey engaged in when developing code for displaying web pages?

Stacey is engaged in client-side programming when developing code for displaying web pages because this type of programming is focused on what happens in the user's browser. Client-side programming involves technologies like HTML, CSS, and JavaScript, which are used to create the visual layout and dynamic behavior of websites that users interact with directly. This includes elements such as forms, animations, and interactive features that enhance the user experience.

In contrast, server-side programming typically involves coding that runs on a web server to manage database interactions and serve content to the client's browser, which is not the focus in this context. Software-defined networking and database administration do not pertain to the direct development of web page displays at the user level, making them irrelevant in this scenario.
