Will It Vibe?Anchor styled as a button via href="#" plus a click handler
Part of Documentation, UX & Accessibility, which counts for 15% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.
What it detects
An <a href="#"> or <a href="javascript:void(0)"> that also carries a click handler is not a link at all: it goes nowhere, so it is being used purely to get a clickable element, which is what <button> is for. Screen readers announce it as a link (implying navigation) and "#" scrolls the page or pollutes browser history when the handler does not call preventDefault. Use a real <button> instead.
Why it matters
An <a href="#"> or <a href="javascript:void(0)"> with a click handler does not navigate anywhere; it exists purely to be clickable, which is exactly what <button> is designed for. Screen readers announce it as a link, setting an expectation of navigation that never happens, and href="#" without preventDefault also scrolls the page to the top or adds a junk entry to browser history.
How to fix it
Replace the anchor with a <button type="button"> and move the existing click handler onto it unchanged; buttons need no href, no preventDefault dance, and are already keyboard-operable. Reserve <a> for elements that actually navigate to a URL or in-page anchor.
