Answer 1

If at all in a simple way.
1. in the source of the page we are looking for something like
2. we make sure that this is exactly the block that we want to remove
3. we prescribe it either in styles, or inline, if acceptable, the style "display: none;"

Answer 2

Don't call header and footer. Although disabling the first will lead to inoperability. See for yourself which files cause unwanted parts of the page

Answer 3

Perhaps a crutch, but I needed to hide on a specific page and purely visually. I used such a design in the page itself. The CSS classes themselves may be different, see for yourself.

<style type="text/css">
.top__container {display:none;}
.header__container {display:none;}
.pt-sticky-menu__container {display:none;}
.footer {display:none;}
</style>
