Flipping Letters Animation
Letters spin a full turn on their vertical axis one after another, like coins flipped down a row, then rest. Each letter carries its own perspective() so the flip has depth without a wrapper.
Also known as: letter flip animation, rotating letters css, 3d flip text loop.

}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.
