You can do either
a) To add code to your document without uploading the files open each file and copy the contents then paste them in the appropriate tags below, in the head of your document. What program are you using to access your files on the server?
CSS:
Code:
<style type="text/css">
CSS FILE CONTENTS
</style>
JavaScript(js):
Code:
<script type="text/javascript">
<!--
JAVASCRIPT FILE CONTENTS
// -->
</script>
b) Linking files. This requires putting the files on your server.
CSS LINKING
Code:
<link rel="stylesheet" type="text/css" href="LOCATION_OF_FILE.css" />
JS LINKING
Code:
<script type="text/javascript" src="LOCATION_OF_FILES.js"></script>
