Contact form 7 not showing properly

Hello mates,
I have a question for you, hope you can help me.
So, my contact form 7 popup with a call to action button on the slider, but I can not see it complete, so I figure out I just have to add more px on top (CSS), but it is located on element.style, so when I try to set it up with chrome inspect element, won´t let me do it in the #fancybox-wrap
It forces me to edit it in the element.style. So, where can I find that? I have my site connected with Dreamweaver.

If you go to the site, and click on “Comienza” button, you’ll see the issue. Also if you have any advices on how to set up the form to fit properly on the screen, I would appreciate it!

Best regards!
