CSS3 implements carousel effect

CSS3 implements carousel images mainly by css: background-position and css3: animation. And to realize this carousel, you need a picture with four pictures connected horizontally.

Note (Internet Explorer 10, Firefox, and Opera support the animation property. Safari and Chrome support the alternative -webkit-animation property.)

HTML:

 <span style="color: #0000ff;"><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="slide-box"</span><span style="color: #0000ff;">></span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span></span>

CSS:

<span style="color: #800000;"><style>
    @-webkit-keyframes slide </style></span>{<span style="color: #ff0000;">

The

animation attribute is a shorthand attribute, JavaScript syntax: object.style.animation=" slide 8s linear infinite", its parameters are as follows:

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

Let the image move within 8 seconds, moving 600px to the left each time, and finally return to the original point. The div is 600px wide, just enough to accommodate one image, thus forming a carousel effect.
