 $('input').on('change',function(){ $('body').css('font-family',$('#font').val()); $('body').css('font-size',$('#size').val()+'px'); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input id="font" type="text" value="input font"/> <input id="size" type="text" value="inpupt size"/> <p> Sample Text </p>

<input id="font" type="text" value="input text font"/>
<input  id="size" type="text" value"input text size"/>
$('input').on('change',function(){
   var font = $('#font').val();
   var size = $('#size').val();
   $('body').css('font-size',size+'px');
   $('body').css('font-family',font);
});
