html - 悬停框并更改顶部的三 Angular 形

Question

我有一个盒子，上面有一个三 Angular 形。两者的颜色相同，但将鼠标悬停在框上时，三 Angular 形的颜色保持不变。

如何改变三 Angular 形的颜色？[在此处输入链接描述][1]

.vw-post-box-read-more {
    position: absolute;
    right: 0;
    top: 0;
    bottom: 0;
    line-height: 1em;
    padding: 20px 15px 15px 15px;
    -webkit-transition: all 0.2s ease-out;
    -moz-transition: all 0.2s ease-out;
    transition: all 0.2s ease-out;
    background-color: #393939;
    /*background-color: rgba(255, 255, 255, 0.15);*/
}
.vw-post-box-read-more .triangle {
    width: 0;
    height: 0;
    border-style: solid;
    border-width: 0 10px 10px 10px;
    -webkit-transition: all 0.2s ease-out;
    -moz-transition: all 0.2s ease-out;
    transition: all 0.2s ease-out;
    border-color: transparent transparent #393939 transparent;
}

<div class="triangle"></div>
<a class="vw-post-box-read-more" href="">
    <span>Read More</span>
    <i class="vw-icon icon-iconic-right-circle"></i>
</a>

您正在尝试设置三 Angular 形的样式，就好像它是 vw-post-box-read-more 的子项一样

试试这段代码:

.vw-post-box-read-more {
  line-height: 1em;
  padding: 20px 15px 15px 15px;
  -webkit-transition: all 0.2s ease-out;
  -moz-transition: all 0.2s ease-out;
  transition: all 0.2s ease-out;
  background-color: #393939;
  /*background-color: rgba(255, 255, 255, 0.15);*/
}
.triangle {
  width: 0;
  height: 0;
  border-style: solid;
  border-width: 0 10px 10px 10px;
  -webkit-transition: all 0.2s ease-out;
  -moz-transition: all 0.2s ease-out;
  transition: all 0.2s ease-out;
  border-color: transparent transparent #393939 transparent;
  margin-bottom: 20px;
}
.hover-box:hover > .vw-post-box-read-more {
  background-color: red;
}

.hover-box:hover > .triangle {
  border-color: transparent transparent red transparent;
}

<div class="hover-box">
<div class="triangle"></div>
<a class="vw-post-box-read-more" href="">
  <span>Read More</span>
  <i class="vw-icon icon-iconic-right-circle"></i>
</a>
  </div>
