Mute Microphone Toggle
A video call mic button: live, it takes the accent and sends out soft ripples; muted, it turns red and a slash draws across the mic, cut out of the icon by a second stroke in the button color.
Also known as: mic mute button css, microphone on off toggle, unmute button.

}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.
