Is there a way to paste the style.css code drop down menu html directly into the html file?

Q: I just purchased your software. I need to set up menus on my DragnDrop
Website Builder. It does not allow ftp uploads or uploads of additional
files. The entire site must be built within their website building platform.

My question is: Since I cannot upload or use the style.css file, is there a
way to copy-paste that code directly into the html file? If so, please
provide exact instructions how to do this.

A: You can paste it directly in the head section of the code of your page inside the <style> </style> tags.
