Call to Action button click does nothing

Hi, on my site, I’ve applied some styling to the call to action button. What I originally had it doing is linking straight to another page on my site. Something happened and now I can click on it, but the button just jumps up the page and nothing else happens. Please help me with what I did wrong. I am very new to Wordpress, so please dumb it down for me. =)

Also, when I shrink the browser window or view on mobile, the description and button disappear. Is this by design? Is there a way to make these appear on any screen size?

Thank you,
