Types like a person thinking: quick bursts, slow dots, a beat before the last word. Each segment of the keyframes has its own steps() count, and the caret only blinks during pauses.
Also known as: realistic typing animation css, human typing effect, typing with delays.

Currently previewing #3b82f6.--txt-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 40px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
