css animation 动画的制作

上效果

效果描述：原来这些图片都绝对定位在最右边，并有一个css3 3D的旋转初始效果。随着动画的开始，依次向左移动，并旋转到0度。（主要用于引导页步骤的描述）

上代码:

html布局

<div class="guidancePage2 col-md-12">
    <div class="pre"><img src="img/pre.png" alt="上一页"></div>
    <div class="step">
            <div class="step_img">
                <div>
                    <div class="step_content"></div>
                    <p>（一）</p>
                </div>
                <div>
                    <div class="step_content"></div>
                    <p>（二）</p>
                </div>
                <div>
                    <div class="step_content"></div>
                    <p>（三）</p>
                </div>
                <div>
                    <div class="step_content"></div>
                    <p>（四）</p>
                </div>
                <div>
                    <div class="step_content"></div>
                    <p>（五）</p>
                </div>
            </div>
            <div class="step_state"></div>
    </div>
</div>

　　css代码，没有做兼容
