How to make a text block link to a form?

I'm trying to create an unsubscribe button just as a text block in my footer, which would link to a form. 

I did try just to use a form button but i'm not looking for this to be a button, but rather just a linked text block.

Thank you!

You can add Text Block, then share link. We can give the CSS to make text link to button.

I know how to add link, but is there a way to when you would click the text "unsubscribe" it would pop up a form or link directly to a form?

There are a number of ways to do this, but if you want to not use code or a button, simply put a form on a page by itself, put that page in the unlinked section of your website, which keeps it off the nav bar, and link your text to that page. When the text is clicked the page comes up with the form open.
