fieldsettags

The fieldset element in HTML is a semantic tag used to group related form controls. It provides a visual and structural way to organize elements within a form, making it more user-friendly and accessible. The fieldset element typically encloses a set of input fields, labels, and buttons that pertain to a specific section of a form, such as personal information, shipping details, or payment methods.

A common companion to the fieldset is the legend element, which is used to provide a caption or title for the group of form controls contained within the fieldset. The legend is usually the first child of the fieldset and is displayed at the top of the grouped elements, serving as a clear identifier for the section.

Using fieldset and legend elements can significantly improve the usability of complex forms. Screen readers and other assistive technologies can interpret these elements to convey the grouping and purpose of form sections to users with disabilities, enhancing their navigation and understanding of the form. Furthermore, browsers often render fieldsets with a border, visually separating the grouped elements from the rest of the form content. This visual separation aids in form comprehension for all users. While not mandatory, employing fieldset and legend is a recommended practice for creating well-structured and accessible web forms.
