Animation-duration:3s

-webkit-animation-duration:3s

(3) animation-timing-function: animation speed curve

Linear: playing at a uniform speed

Ease: the animation starts slowly and then speeds up and slows down at the end (default)

Ease-in: animation starts at a low speed

Ease-out: refers to the animation ends at a low speed.

Ease-in-out: animation starts and ends at a low speed

Cubic-bezier: set the desired value from 0 to 1 in the cubic-bezier function.

Animation-timing-function:ease

-webkit-animation-timing-function:ease

(4) animation-delay: delay time for the start of animation

Animation-delay:3s

-webkit-animation-delay:3s

(5) animation-iteration-count: the number of times the animation is played

N: the number of times to customize the playback of the animation
