Animated Price Counter
A pricing-table price counts up to $49 while the cents spin through their digits and land on .99. Dollars and cents are two registered integers; the cents pad to two digits with a counter style.
Also known as: price counter animation, pricing number animation, counting price css.

}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.
