Sound On Off Toggle
A mute switch with a speaker in the knob: off shows a cross, on draws two sound waves and sets a five-bar equalizer bouncing in the track. Each bar gets its own speed and delay from --i.
Also known as: mute unmute toggle css, volume toggle switch, speaker icon toggle.

}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.
