header için bunu
<header><meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"><link rel="stylesheet" type="text/css" href="https://s3.eu-central-1.amazonaws.com/shopier/static/css/shopiermodal.min.css"><link rel="stylesheet" type="text/css" href="https://s3.eu-central-1.amazonaws.com/shopier/static/font-awesome/css/font-awesome.min.css"></header>


footer için

<script>window.onload = function () {$.getScript('https://s3.eu-central-1.amazonaws.com/shopier/static/js/gsap.js', function(){$.getScript('https://s3.eu-central-1.amazonaws.com/shopier/static/js/shopiermodal.min.js', function(){$.getScript('https://s3.eu-central-1.amazonaws.com/shopier/framework.js', function(){console.log( "ready!" );});});});}; </script>

bunu ekledim.

<a href="#" class="shopier" id="5239785">SATIN AL</a>

bu kod fontu bozuyor
<link rel="stylesheet" type="text/css" href="https://s3.eu-central-1.amazonaws.com/shopier/static/css/shopiermodal.min.css">
