Pop-up Portfolio Images under the footer

Hello!

Before anything else let me say that I’m very happy with this theme :) Thank you!

Now… I have a problem. The images from my pop-up portfolio (which are in my homepage) are shown all smushed and behind the footer. This appears to be a problem just for laptops or PCs, since the website works just fine on mobile devices.

Any idea of what can it be and how can I solve it?

By the way, is there a way to decrease the font size from the header? If you open the website on a mobile device the phrase CARLOS CAMARÓN is cut (CARLOS CAMARO-N).

Thank you!
