Can uwp be implemented on a pure front end?

ask the development boss of uwp,
because there is no experience in c-sharp and xmln,
wants to know whether
uwp can only be realized by html css js because it wants to know that app uses the shell of web page to achieve uwp,.
and the development process of uwp?
is looking at the relevant content of msdn. Is there anything that needs the attention of beginners?
