This page tests methods for embedding powerpoint presentations on web pages. The presentation is a quick example that includes a link to another slide (3 energy) and an embedded video.

Powerpoint presentation embedded from OneDrive

Powerpoint presentation embedded from Google Docs

I found it easier to edit the file in Powerpoint for desktop first, as inserting links is fiddly in the online version of PPT. It’s a lot easier in Google Docs. The page displays alright but does not look as good on mobile devices due to the small text and video.
