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

![在这里插入图片描述][20210105164416827.gif_pic_center]

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>
    
                <transition name="fade"
                            @before-enter="beforeEnter"
                            @enter="enter"
                            @after-enter="afterEnter">
                    <div class="ta-show" v-if="show">
                        <div >
                            
                            <div class="job-line"  id="line"></div>
                            <div class="j-tips" id="word">{

                    font-family: SourceHanSansCN-Medium, SourceHanSansCN;
                    font-weight: 500;
                    color: #FFFFFF;
                    line-height: 51px;
                }
                .j-tips{

            }
    
    
    
        }
    }
    </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%;
        }
