## Solution

Invalid links (malformed URLs, javascript: links, or broken references) harm user experience and can indicate code issues. Fix or remove invalid links. Replace javascript:void(0) with proper href values or button elements. Ensure all links have valid URL formats. Check for typos in URLs and verify links work correctly. Remove empty href attributes.
