Vue 2.x 转换不适用于 Html 标签 ID CSS

Question

只是好奇这是否是 vue 的预期行为，或者可能有一些我没有看到的潜在 CSS 逻辑？

当使用 class 选择器

.theBoxClass { right: 100px;}

但使用 css ID 选择器设置时不会

#theBoxId { right: 100px;}

代码

<div id="background"></div>

<script src="https://unpkg.com/vue/dist/vue.js"></script>

<div id="vue">
  <transition name="slide">
    <div id="theBoxId" class="box" v-if="show">ID</div>
  </transition>

  <transition name="slide">
    <div class="theBoxClass box" v-if="show">Class</div>
  </transition>
  <button v-on:click="onShowClick">CLICK ME TWICE</button>
</div>


body {
  margin: 0;
  padding:20px;  
}

button
{
  background:red;
  padding:30px;
  color:white;
  font-weight:bold;
}

.box{
   background:gray;
  width:100px;  
  position:fixed;  
  height:100px;
  text-align:center;
  color:white;
  font-size:20px;
  line-height:100px;  
}
.theBoxClass
{
  top:20px;
  right:100px;
}

#theBoxId
{
   top:220px;
   right:100px;
}


    .slide-enter-active , 
    .slide-leave-active {
      transition: right 1s ease-out;    
    }

    .slide-enter,
    .slide-leave-to  { 
       right:-100px;
    }



new Vue({
  el: "#vue",
  data: {  
    show: false
  },
  methods: {
    onShowClick: function() {
      this.show = !this.show;
    }
  }
});

Answer 1

改变

.slide-enter,
.slide-leave-to  { 
   right:-100px;
}

到

.slide-enter,
.slide-leave-to  { 
   right:-100px !important;
}

使其与 ID 一起工作，因为 ID 选择器的 specificity 多于 class 选择器：

The following list of selector types increases by specificity:

• Type selectors (e.g., h1) and pseudo-elements (e.g., ::before).

• Class selectors, attributes selectors and pseudo-classes.

• ID selectors (e.g., #example).
