Explain the use of the <fieldset> and <legend> elements for grouping form controls.

The <fieldset></fieldset> element can significantly improve the accessibility of forms in several ways:

1. Structural Organization: By grouping related form elements, <fieldset></fieldset> provides a clear structure to the form, which is beneficial for users navigating with assistive technologies like screen readers. These technologies can announce the start and end of a fieldset, helping users understand the form's layout.
2. Enhanced Navigation: Users, especially those using keyboard navigation, can more easily move through the form when it's divided into logical sections. This can reduce the cognitive load and make the form more manageable.
3. Improved Focus Management: When a <fieldset></fieldset> is used, it can help in managing focus more effectively. For instance, if a user tabs through the form, they can understand when they are entering or leaving a group of related controls.
4. Semantic Meaning: The use of <fieldset></fieldset> adds semantic meaning to the HTML, which is crucial for accessibility. It tells assistive technologies that the enclosed elements are part of a group, which can be announced to the user, thereby improving their understanding of the form's structure.
