Hi just posting this quick tutorial on how to create a hidden or invisible link you can also hide input form and textarea the same way, this can be used to let say fool some spambots making them believe that it's a required field in case of input field.
Here the link is invisible but still takes up space
<a class="hidden" href="url">TextHere</a>
<a href="url" style="display:none">Error</a>
<a href="url" style="visibility:hidden">Error</a>
