How to achieve three-dimensional effect in html5

html5 Method to achieve three-dimensional effect: 1. Create an HTML sample file; 2. Pass ".img {width: 50px; height: 50px; margin: 0 auto; transform-style: preserve-3d;} " attribute to achieve a three-dimensional effect; 3. Use the "@-webkit-keyframes rotate {...}" attribute to achieve the animation effect.

HTML5 Special Effects~3D Cube Rotation

Let’s first appreciate the final effect of this special effect

#

该特效是基于Css3的一些新特性拼接而成.主要用到了hover,transform和@keyframe属性.下面简述一下这三个属性的作用.

hover

效果:当鼠标移到元素上时会展现你定义的hover的样式

使用方法:假定我们有一个类,名为mystyle.修改它的css样式的方式是.mystyle{}.修改它的css hover样式的方式是.mystyle:hover{}.

transform

效果:对元素进行旋转、缩放、移动或倾斜

使用方法:传入旋转rotate(angle),缩放scale(x,y),移动translate(x,y),倾斜skew(angle)的参数进行属性的修改

@keyframe

效果:实现动画效果

使用方法:@keyframe 后 动画名{from:初始状态;to:末状态}

代码解析

<style>    /*实现立体效果*/
    .img {
        width: 50px;
        height: 50px;
        margin: 0 auto;
        transform-style: preserve-3d;        
        /*设置动画播放样式:动画对象 播放速度 时间 播放次数*/
        animation: rotate linear 20s infinite;
    }    /*实现动画效果*/
    @-webkit-keyframes rotate {                /*sofari chrome*/
        from {
            transform: rotateX(0deg) rotateY(0deg);
        }
        to {
            transform: rotateX(360deg) rotateY(360deg);
        }
    }    /*图片样式*/
    .pic{
        width: 200px;
        height: 200px;
        transform: rotateY(0deg) translateZ(100px);
    }</style>
