I've been struggling to modify this button, and even tried incorporating bootstrap javascript without success. Below is a snippet of the code I'm working with. Any guidance on how to achieve this would be highly appreciated.
<html>
<head>
<script type="text/javascript" src="assets/js/bootstrap-filestyle.js"></script>
<script>
$(":file").filestyle({input: false});
</script>
</head>
<body>
<input type="file" class="filestyle" data-input="false">
</body>
</html>
