Random

The random() function is available on Safari Technology Preview and I had to give it a try.

So I created the typical comic with characters breaking the 4th wall (actually being self-aware characters, but that's a technicality), confused about the order of the panels not being correct... something easily achieved with the random() function!

css-comic {
css-panel { order: random(2, 900); } /* panels in random order */
footer { order: 1000; } /* footer always last */
}

A fun thing about this comic is that there are 24 (4! = 4 x 3 x 2 x 1) different versions of it. So each time that you reload the page, it may be different from the time before.

You can check out the comic on this CodePen. And remember: it only works on Safari Technology Preview at the moment.

*EDIT: I added a second version with other test that I think would be better for this.
