I can click on a link outside of its text element?

I have a h3 link somewhere at the bottom of a page and not only does the link expand to the whole row, but also in a row higher than the h3 element. I'll explain better using this screenshot:

Where the arrows are pointing at is where I can actually click the link outside of the h3 element (Become part of the innovation is the actual link). Any ideas on how to make the link be clickable only on the text and what is causing this?
