Custom Fonts not available in all browsers / devices

Hi @tuanphan

I've been having some troubles with the CSS Custom Fonts. I can't see the fonts properly in all browsers / devices. I have noticed that normally H1, H2, H3 are working fine but I can't see the Klavika font on body text or blogs.

Please find in the lines below the CSS inserted:

All fonts have been uploaded as .ttf, .otf, .woff, and .woff2.

h1 {
font-family: 'KLAVIKA BOLD', 'futura-pt', 'sans-serif', !important;
font-size:40px;     
}

h2 {
font-family: 'KLAVIKA MEDIUM', 'futura-pt', 'sans-serif', !important;
font-size: 20px; 
}

h3 {
font-family: 'KLAVIKA MEDIUM', 'futura-pt', 'sans-serif', !important;    
font-size: 15px;  
}

body {
font-family: 'KLAVIKA', 'futura-pt', 'sans-serif';
font-size:20px;     
}

nav a {
font-family: 'KLAVIKA', 'futura-pt', 'sans-serif';
}

.desc-wrapper p > strong {
font-family: 'KLAVIKA MEDIUM', 'futura-pt', 'sans-serif';
}

.BlogList-item-title, {
font-family: 'KLAVIKA', 'futura-pt', 'sans-serif', !important;
font-size: 25px;
}

.BlogItem-title {
font-family: 'KLAVIKA BOLD', 'futura-pt', 'sans-serif', !important;
font-size: 40px;
}

.Header-nav--primary .Header-nav-item {
  font-family: 'KLAVIKA MEDIUM';
}
.Mobile-overlay-nav--primary .Mobile-overlay-nav-item {
  font-family: 'KLAVIKA MEDIUM' !important;
}

.BlogList-item-excerpt {
  font-family: 'KLAVIKA', 'futura-pt', 'sans-serif';
  font-size: 14px;
  color: #616161;
}

.BlogList-item-readmore {
  font-family: 'KLAVIKA', 'futura-pt', 'sans-serif';
  font-size: 14px;
  letter-spacing: 0.19em;
  color: #616161;
}

.sqs-block-summary-v2 .summary-read-more-link {
 font-family: 'KLAVIKA', 'futura-pt', 'sans-serif';
  font-size: 14px;
  letter-spacing: 0.1em;
  color: #616161;
}

Thanks a Million!

body/blog font didn't work? or 

It works on this device, and doesn't work on other devices?

And where do you get the above code? Are you sure the class name is correct?

It works in this device but not on mobile or other browsers, for example safari.

The code above is under: Design/ Custom CSS. It could be that some class names are not correct. Could you take a look?
