to reproduce this consider eg using fonts.google.com (free fonts ,apache license) by adding after the link google provided (if you use that in production remember to download all zip and include copyright text) : &text= ...

http://fonts.googleapis.com/css?family=Cabin+Sketch&text=1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz%20

then to replicate the given example with another font (similar .woff2 ,from anywhere ,free copyright) download any apache php server ,create a folder "argonexample" ,edit a index.php inside

put this and a file font.woff2 (inside that folder)

<?php
header('Content-type: text/css');
?>@font-face {
  font-family: 'Noto Sans Display';
  font-style: normal;
  font-weight: 100;
  font-stretch: normal;
  font-display: swap;
  src: url('data:application/font-woff2;charset=utf-8;base64,<?php
    echo( base64_encode(implode('',file('font.woff2'))));
?>') format('woff2');
}

after you call it localhost/argonexample/ you should get similar output:

@font-face {
  font-family: 'Noto Sans Display';
  font-style: normal;
  font-weight: 100;
  font-stretch: normal;
