Mute Unmute Button
A round speaker button: click and the sound waves collapse back into the speaker one after the other while a slash draws across it. The slash is stroked twice, once in the button color to cut a gap.
Also known as: mute button animation css, sound toggle button, volume icon toggle.

}Customizing this snippet
- Color: set
--btn-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--btn-size. Every other dimension is inem, so the whole thing scales together. Currently previewing18px. - 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.
