Typewriter Effect
Text types itself out one character at a time behind a blinking caret. Pure CSS: the width steps up one character per frame using ch units, so set the step count to your text's length.
Also known as: typing animation, typing text effect, terminal typing.

}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.
