#default but they are ticklish

u/gabornyeki

I was hoping that this would work with the "touchstart" event in Safari but it doesn't. But it does respond to clicks!

Fixed the colors and just barely managed to squeeze in a loop to speed it up

Ooops, looks like the }{ trick broke. Sorry :|

u/AnnanFay

Laptop only?
u/dwardu

Works on mobile/laptop, but on desktop appears as “100% & charging.” I would have liked to tackle this by modifying the expression to “ℓ<1&&b.charging?t%ℓ:ℓ”, but I couldn’t find a way to reduce a further 5 characters!
u/dwardu

Could be written as “ℓ<1&”, so 4 characters really.
u/AnnanFay

Hmm, on desktop-windows-firefox I'm just getting "navigator.getBattery is not a function"
u/AnnanFay

Ah, this would explain it: "From Firefox 52 onwards, the Battery Status API is only available in chrome/privileged code."
u/dwardu

Yes, after your comment I did some research and made this discovery too.
