Flip In Y: CSS Keyframe Animation

Flip In Y

Turns in on its vertical axis like a card being flipped face up, with one ease-out back overshoot instead of a wobble. Starts edge-on, so the back face never shows.

Also known as: flip in y css, card flip in animation, flip in vertical axis.

Customizing this snippet

Color: set --kfa-color on the element or a parent. Currently previewing #3b82f6.
Base size: set --kfa-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
Speed: change the duration on the transition or animation shorthand. 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.
