HTML5 's FieldSet label

Definition and usage

The FIELDSET element groups related elements within a form, drawing a caption, like a panel in a WinForm development.

<fieldset> tags Package a portion of the form's content to generate a field for a set of related forms. The <fieldset> tag does not have a required or unique attribute.

When a set of form elements is placed inside the <fieldset> tag, the browser displays them in a special way, they may have special boundaries, 3D effects, or even create a sub-form to process the elements.
