纯 Css 实现关闭按钮

使用 span 标签

通过伪类 before after 添加两个左右倾斜 45 度的长条构成关闭按钮

通过 hover 实现鼠标移动上去变色

<template>
  <span class="close"></span>
</template>

<style>
  .close {
    position: relative;
    display: inline-block;
    width: 50px;
    height: 50px;
    overflow: hidden;
  }
  .close:hover::before,
  .close:hover::after {
    background: #1ebcc5;
  }
  .close::before,
  .close::after {
    content: "";
    position: absolute;
    height: 2px;
    width: 100%;
    top: 50%;
    left: 0;
    margin-top: -1px;
    background: #000;
  }
  .close::before {
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    -o-transform: rotate(45deg);
    transform: rotate(45deg);
  }
  .close::after {
    -webkit-transform: rotate(-45deg);
    -moz-transform: rotate(-45deg);
    -ms-transform: rotate(-45deg);
    -o-transform: rotate(-45deg);
    transform: rotate(-45deg);
  }
</style>
