What will be the outcome if the HTML links are missing a valid URL?

When HTML links are missing a valid URL, the outcome is that a broken link will be created. A valid URL is necessary for a hyperlink to function correctly; without it, the link cannot direct users to the intended destination.

When a user attempts to click on a link that does not have a valid URL, it does not lead anywhere, which results in a broken link. Depending on the browser and the specific implementation, this may manifest as the link appearing inactive, leading to an error page, or simply failing to perform any action.

This situation highlights the importance of ensuring that all links in HTML are correctly formatted with valid URLs to guarantee proper navigation and a positive user experience. HTML will execute without errors even if a link is broken, as the markup itself is still structurally valid, but the functionality of that link is compromised.
