关于appear的用法和enter的用法相似，它只是在第一次渲染的时候才会起作用。看完整的代码：

别忘了引用vue.js

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>初始渲染的过渡</title> <script src="vue.js"></script></head><style> .custom-appear-active{  color: #2fe26d;  background: #b6b6b6;  transition: all 1s ease; } .custom-appear{  font-size: 40px;  color: #e069e2;  background: #7798e2; } .custom-appear-to{  color: #e29138;  background: #1c8942; }</style><body><div id="app"> <transition   appear   appear-class="custom-appear"   appear-to-class="custom-appear-to"   appear-active-class="custom-appear-active" >  <p>appear</p> </transition></div><script> new Vue({  el: "#app" })</script></body></html>

但是这里有一些问题：关于appear-class、 appear-to-class、 appear-active-class的相同属性那个起作用的问题。

四种情况：（与他们在style中的排列顺序有关系）

1、appear-class、 appear-to-class、 appear-active-class或者 appear-to-class、appear-class、 appear-active-class的排列顺序，此时只有appear-active-class的属性起作用。

2、appear-active-class、appear-class、 appear-to-class

此时appear-active-class的不起作用，由appear-class过渡到appear-to-class属性。

3、appear-class、appear-active-class、 appear-to-class

此时appear-class属性不起作用，由appear-active-class过渡到 appear-to-class属性。

4、 appear-to-class、 appear-active-class、appear-class

此时appear-to-class不起作用，由appear-class过渡到 appear-active-class属性。

enter也有相似的问题
