I noticed that I cannot add stylesheets on any page. They must be added to the master page.
I already have about 15 stylesheets in the master view, which seems like overkill, since only some of the pages use a certain stylesheet.
I imagine I could reference the file via javascript (although, I can’t think of how off the top of my head), but it would be really nice to not have to use any.
You should be able to add them to the head placeholder on the content pages…
