Is it possible to upload a file to a website, only by modifying the HTML and CSS code?

Question

I'm trying to upload a file to a website, so I can download it later from another location. Is there a way to do this solely by modifying the HTML/CSS code of the website?

Answer 1

No. Neither HTML nor CSS are programming languages (meaning they allow you to interact with the server and its files) and, if it were allowed, anyone could upload files to a site's server.

Answer 2

Yes. You just need to modify the HTML/CSS code of the website.
