Custom H5 Font Mobile Issue

I've added a custom font / H5 headline that isn't working on mobile. Any idea why?

Code I'm using:

h5 {      
font-family: lulo outline !important;  
font-weight: bold;  
font-size:3.2em;
color: #F1F0E5;  
text-transform:uppercase;
text-align: center;  
letter-spacing: 0em;  
line-height:1.4em;  
margin:0px;

}

I think what's happening is that it doesn't just not work on mobile, it doesn't work anywhere that I look at it, it only seems to work on your computer.

Can you share the rest of your Custom CSS so we can see if there's an issue there?
