Availability of top navbar items to assistive technology requires the use of aria-controls.
Navbars must be contained in <nav> elements with unique accessible labels for each navigational element on the page, if there’s more than one.
The name of each item should include the attribute role="button".
Provide a label for all menu items that can be read by assistive technologies. You may use visually-hidden text or add an aria-label to each menu item. If you need the menu item name to be translatable, use visually-hidden.
