What is a field set in the context of web forms?

In the context of web forms, a field set refers to a grouping of fields that are related to each other. This concept is especially useful for organizing forms that contain multiple related inputs, enabling better structure and clarity for users filling them out. For instance, a field set might group together inputs for personal information such as name, address, and phone number, which makes it clear to users that these fields are related to a single category.

Using field sets can enhance the accessibility of a form as it allows screen readers to communicate to users that the contained fields are part of a collective group. This organizational strategy aids in user experience, ensuring that forms are not only easier to navigate but also visually distinct and logically structured.

Other options such as a type of input field, a specific data type, or a layout design element do not accurately encompass the function of a field set, which is fundamentally about the logical grouping of multiple input fields rather than singular elements or design aspects.
