Wordpress or html one page

I have this idea and I wonder if someone is able to implement it wisely and well.

It needs a One Page based on wordpress or not, which would look as follows:

There is only one screen that fills the whole area, no scroll bars, both mobile and desktop.

On the screen at the top left logo and menu, in mobile in the middle logo and hamburger

At the very center the caption: How can I help you? Which animates into various texts like "You have a problem with Amazon.... I'll help" texts of course can be somewhere in the code, it would be nice if they would randomly appear.

And if someone wedges in this text a simple form develops:

How can I help you - description

Name:

Phone or email as you prefer:

Send button

possibly some small footer, menu type or text.

Of course, the form must work :)

if you have any questions, please let me know

Best Regards Adrian
