The **Side Navigation** is an in-page navigation element that allows users to understand the contents of a page or navigate a paginated step-by-step instruction. It is most closely associated with the In-page Navigation Component in the U.S. Web Design System (USWDS) with a few key differences. --- The **Side Navigation** is used by the [Step by Step](step-by-step) pattern to create a paginated experience that helps users understand how to apply to public benefit programs. --- The `nav` element must have a unique `aria-label` attribute to help screen readers distinguish it from other `nav` elements. Recommendations for the label from the USWDS include "On this page," "In this article," or "Table of contents."
