We have created some custom SharePoint hosted add-ins and added them on to a Page. These add-ins have some custom styles that are common however, they are not shared.
Is there a way by which I can put these custom styles in a common location (i.e. outside the add-in web) and access the same file across these different addins? I also dont want to load the shared css file to to be loaded indidvidually for each of the add-ins?
Yes, I too had thoughts around this, however (probably I forgot to mention) my solution is hosted in SharePoint OnPremise and not in Office 365/SPOnline. Secondly this is still in developer preview... so believe not recommended for a PROD deployment.
