So I suspect it may also have to do with what browser one is using, and specifically, how current your browser is with all the latest HTML features. Over the last some-number-of-years, browsers have been implementing various HTML5 capabilities little by little, and I think more and more web sites are using HTML5 stuff. My relatively ancient Firefox browser, for example, seems to implement some of the new HTML5 specs but not a whole lot.
If you wanted a word for Google Doodles, would you call them Goodles or Doogles?
ETA: IIRC, there exists a web site somewhere (maybe part of the W3C stuff at www.w3.org perhaps?) that somehow runs interactively with your browser and tests HTML5 features, and gives you a report on what works and what doesn’t. Anybody here know exactly what that site is?
