I have a Mathematica notebook that contains some animations based on numerical solutions to differential equations, with a few input parameters (either directly typed in or using sliders). I can't find a tutorial (either online or within the Help system) on how to convert this into an online web file that my students can explore for themselves. Ideally, it should show all the same content as the nb, but also be able to actually run the animation, with students being able to change the input. I tried simpleminded commands like "Export", but although a bunch of html files were created, they don't seem to do anything in my browser (Safari). Any hints would be appreciated!
