PopUp Pro Window Alignment on mobile (iPhone) & Control Appearance Animation

I have a site (http://fontdont.com/bp/) that I'm working on. When I use the "Never see this message again" option, it gets cut off on an iPhone 5s (it only shows "Never", before getting cut off on the right side - it's going off the page). Is there a fix for this?

Also, I'm wondering if it's possible to control the appearance animation timing. It appears instantly and it's a bit startling. I'm hoping to animate the appearance to 0.5 seconds, so it appears a bit softer. Is this possible?

Thanks for your help!
