vue项目开发引导页-带有动画效果，如下图所示
本案例实现步骤是:
1，先开发一个全局的弹框（遮罩层）全局弹框代码-遮罩层
2，添加背景图-使用绝对定位实现元素定位
3，开发带有动画效果的组件

实现动画效果的代码如下所示，PositionGuide.vue：

<template>
    <div class="re-guide">
        <div class="re-content">
            <div class="re-cbtn" v-if="step=='one'">
                <div type="primary" class="btn-block" >

                    <span class="btn-edit"></span>
                    <span class="btn-word">发布新职位</span>

                </div>

            </div>
            <div class="g-btn" v-else>
                <div class="btn-tr">
                    置顶
                </div>
            </div>

                <div class="ta-show" v-if="show">

                        <div class="job-line"  id="line"></div>
                        <div class="j-tips" id="word">{{info}}</div>
                        <div class="ta-btn" id="btn">

            }
        }



    }
}
</style>

在需要引入的地方引入组件PositionGuide.vue

template v-if="firstFlag">
            <div class="pos-bg">
                <my-dialog :visible="firstFlag">
                    <PositionGuide @positionFun="positionFun"></PositionGuide>
                </my-dialog>
            </div>
        </template>

pos-bg的样式为：

.pos-bg{
        width: 1100px;
        margin: 0 auto;
        height: 84vh;
        background: url("../../assets/img/newPic/job_bg.png") no-repeat;
        background-size: 100%;
    }

my-dialog请参考链接my-dialog
