Chat Bubble Typing Animation
A chat bubble pops in with three bouncing dots, then stretches open and the message fades in where the dots were. The bubble grows with an animated clip-path, so nothing reflows.
Also known as: typing indicator to message, chat message animation css, messenger typing bubble.

}Customizing this snippet
- Color: set
--txt-coloron the element or a parent. Currently previewing#3b82f6. - Font size: set
--txt-size. Every other dimension is inem, so the whole thing scales together. Currently previewing40px. - 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.
