html , css , js

Hello can someone please tell me how to upload html , css , js on sitebuilder website ?

-Thanks

The purpose of the site builder is to be able to build a website without coding. Because of that, it can’t actually be used to submit your own website code.

If you already have your own website coded up which you want to use, you can just ignore the site builder and upload your files directly to your hosting account using FTP or a file manager.
