Custom code - email line length

Site URL: http://jajaphotography.com/

Hi, I'd like to force the email to be on one line when viewed on mobile, Please see screenshot attached.

I have tried this, but it doesn't work. Really need your help. 

/* Mobile-scrolling text */
@media screen and (max-width:750px) {
.scroll {
    white-space: nowrap !important;
    overflow: visible !important;
}

Thanks

footer.sections [href*="mailto"] {
    font-size: 16px;
    white-space: nowrap !important;
}
}
