Need to Fix Site On Mobile Devices

Hi,
I have support access on for p4kdating.com.

Here is what the client said:
o the words are fixed on the desktop version but not it’s not right on the phone version. Is there a way the words can be smaller. At first it looked good on the phone but now who ever fixed it has it not cut off on desktop but cut off on mobile version of site. Screen shot attached. Could lettering be smaller??? So that words aren’t cut off on both desktop and mobile???

The link to the screen shot is:
