I tend to forget that there’s a million ways to animate things. Here’s some ways. This will probably be a mish-mash of technical methods as well as things that can actually be done.
Also worth noting: I use Firefox full time, and I’m not cross-browser-compatibility-testing anything here. This is mostly for the sake of reference. Maybe I’ll go back through and add cross-browser usage notes, where applicable. Or not.
This is also, like some of my graphics experiments, sort of a rough sketchbook of ideas. So there’s themes and variations and it’s sometimes in a logical order but the list might also swerve from time to time when I jump topics or ideas or libraries or whatever. Not to be treated as an exhaustive tutorial.
