Subpages without wordpress

Hi folks,

i created a wordpress-site with some subpages as a landing page.
the sitemap would look similar to this:
– https://domain.com/
– https://domain.com/subpage1
– https://domain.com/subpage2
…

What i would like to have now are subpages with the same domain, but without wordpress around it. I would need just blank pages (no fancy wordpress functions or styling from my theme) for example:

– https://domain.de/otherpage1
– https://domain.de/otherpage2

It would be also OK if i could use a wordpress page where i would place some content on but which does not get styled by the active theme. A blank page would be great ??

Any ideas how i could accomplish that?

Thanks in advance
Daniel
