How do I sign in to my "website"?

Go to your hosting site, look for something that says Control panel. That is where you log into the utility that allows you to do everything for your site. Find File Manager. That is where you will be able to edit files and there should be a File Uploader utility. If your site allows FTP, download and use free FileZilla and login using it to upload multiple files that you've edited on your hard drive.
