Restructuring openPASS

Currently, the openPASS webpage is not structured well and for external parties not really helpful. The openPASS WG received some feedback which we want to apply to the webpage. To get a better idea of how we want to design the webpage the Draftium editor was used: https://bpxlu.draftium.site. We want to start with the title page. After this has be done the subpages are going to be adressed.

Would it be possible to implement the changes to our current webpage?
