Rule: html-anchor-require-href
An <a> element that has an href attribute represents a hyperlink (a hypertext anchor) labeled by its contents. Links should go somewhere. If you want to perform an action without navigating the user to a new URL, use a <button> instead.
Anchor tags without an href attribute are not focusable via keyboard navigation and are not visible to screen readers. This makes them inaccessible to users who rely on assistive technologies.
