Let’s first introduce the definition and usage of animation

The animation attribute is a shorthand attribute, used to set six animation attributes:

    animation-name
    animation-duration
    animation-timing-function
    animation-delay
    animation-iteration-count
    animation-direction

Default value: none 0 ease 0 1 normal

Note: Please always specify the animation-duration attribute, otherwise the duration will be 0 and the animation will not be played.

Syntax

 animation: name duration timing-function delay iteration-count direction;

animation-name can specify the keyframe name that needs to be bound to the selector. .

animation-duration Specifies the time it takes to complete the animation, in seconds or milliseconds.

animation-timing-function Specifies the speed curve of animation.

animation-delay Specifies the delay before the animation starts.

animation-iteration-count Specifies the number of times the animation should be played. (Value: n times, infinite loop)

animation-direction Specifies whether the animation should be played in reverse in turn.

Summary:

Based on the above attributes, you only need to set animation-delay and animation-iteration-count according to the specific situation.

For example:

p
{
animation:mymove 5s 5s infinite;
-webkit-animation:mymove 5s 5s infinite; /* Safari 和 Chrome */
}

Solution example:

<!doctype html><html lang="en"><head>
 <meta charset="UTF-8">
    <title>Document</title>
    <style>
        .item1{
         list-style: none;
         -webkit-animation: revolving 4s 0s infinite;
         animation: revolving 4s 0s infinite;
        }
        @-webkit-keyframes revolving{
         0,75%{
        -webkit-transform: perspective(700px) rotateX(90deg);
         }
         87.5%{
        -webkit-transform: perspective(700px) rotateX(0deg);
         }
         100%{
        -webkit-transform: perspective(700px) rotateX(-90deg);
         }
        }
    </style>
</head>
    <body>
        <ul>
            <li class="item1">梅西与美洲杯失之交臂</li>
        </ul>
    </body>
</html>

Set the total animation to 4 seconds, and then the first 75%, which is 3 seconds, will not change (0- 75%), and the next 25% is just 1 second for animation.
