Open HTML files in browser - SharePoint Online

amwreck  Hope I am replying to the right place.

I think I have a break in the case.  It's not perfect, and it is rather cumbersome and will be a ton of, but it works.  It's better than hosting on the school's general website because I don't have access to it and I will always have to beg people to do things for me.

So, the thing I did was under "site pages" (on the left), clicked on that and opened a new "wiki."  I name it, then over on the upper right I click "edit."  The ribbon shows up and near the upper right I click "edit source."  From there, I just cut and paste my old html source code into the window.  You have to hit "OK" at the bottom, and then "Save" (upper left...or sometimes right).

This will create an aspx page which can be edited more like a word document (so the style sheet is no longer necessary).  You can string the pages together by substituting the new full link to the new sharepoint page ending in aspx.  (It seems to shorten them automatically to the root stem, but it works...such as https://nycda.sharepoint.com/sites/nydramalibrary/SitePages/BooleanExamples.aspx  (where formely in my html site I just had to put BooleanExamples.html.  Now it shortens it automatically to just https://nycda.sharepoint.com/sites/nydramalibrary/SitePages/BooleanExamples.aspx

Now for the photos.  I dumped them into their own document library and submitted the long file path to those.  Something like https://MYSCHOOL.sharepoint.com/sites/nydramalibrary/IL100%20Tutorials/booleanexamples.jpg  (whereas in my old site all I had to put was booleanexamples.jpg).

This is the only workaround I have been able to devise and like I said, it will be kind of a BE-ATCH to do for 300 html files, but at least it seems doable.
