Rocket Launch Toggle
A vertical space switch: turn it on and the rocket lifts off the pad in a puff of smoke, its flame flickers and the stars stream past. Turn it off and it settles back down to land.
Also known as: rocket toggle switch, vertical toggle rocket, space launch switch css.

}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.
