Slide Out Right
Accelerates off to the right and fades on the way, like a dismissed notification or a swiped card. The ease-in curve keeps it readable at the start, and the distance is in em so it scales.
Also known as: slideOutRight, css slide out animation, slide out to the right css.

}Customizing this snippet
- Color: set
--kfa-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--kfa-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - 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.
