Unfold Text Animation
A line draws across the middle, then the text unfolds out of it vertically with a little overshoot, like an old TV warming up. The line is a pseudo-element; the text only animates scaleY.
Also known as: scale y text reveal, open from line animation, tv turn on text.

}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.
