I'm working on a website where I would like to embed Google Calendar. I would like to be able to add a small icon next to certain events. I can use the "categories" section of Google Calendar to add a highlight color to the events, but in addition to that, I'd like to specify that some events have food by putting a small fork-and-knife icon next to them.
The only material I could find online about something like this is Google's Event Flair Lab, which not only didn't work for me, but from research appears to have been abandoned. Perhaps there is a way to program this myself?
I'm open to suggestions about other free calendar systems that make this possible other than Google Calendar. Please let me know if you need any other information - this seems like a fairly simple project, but I can't find any information on how to accomplish it.
