Notification Bell Toggle
Turn notifications on and the bell rides across, rings with a decaying swing while its clapper knocks the other way, and a red badge pops in. Off, a slash is drawn back over it.
Also known as: bell toggle switch css, notification on off switch, ringing bell animation.

}Customizing this snippet
- Color: set
--tgl-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--tgl-size. Every other dimension is inem, so the whole thing scales together. Currently previewing24px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
