What function does CSS serve in OutSystems applications?

CSS, or Cascading Style Sheets, plays a critical role in designing and styling the user interface of web applications, including those built with OutSystems. It is responsible for defining how HTML elements are displayed on the screen. This includes setting properties like color, font size, layout, spacing, and overall aesthetics of the web pages.

In the context of OutSystems applications, CSS is employed to create custom styles that enhance the visual appeal and user experience of the application. By applying CSS, developers can ensure that their applications not only function well but also present a polished and user-friendly interface. This is essential for engaging users and ensuring that applications are not only functional but also visually attractive.

The other choices primarily relate to backend operations or data handling, which are not the focus of CSS. For instance, managing database connections and improving backend processing pertain more to server-side functionality. Generating reports typically involves data manipulation and presentation logic, which is also outside the scope of CSS. Thus, the role of CSS as a styling language is the clear and appropriate function within OutSystems applications.
