1. Customize the calendar component

It has been packaged into a vue component, and you can choose to switch the year and month:

<template>
  <div class="calendar-container">
    <div class="year flex items-center">
      <el-config-provider :locale="local">
        <el-date-picker
          v-model="selectDate"
          @change="rsetDate"
          type="month"
           class="testDate"
            popper-class="dark_form"
          style="width: 1.2rem"
          :placeholder="nowDate.year + '-' + (nowDate.month + 1)"
        >
        </el-date-picker>
      </el-config-provider>
      <div class="img"></div>
    </div>
    <ul class="week flex">
      <li v-for="(o, index) in 7" :key="o">{
   
   { formatWeek(index) }}</li>
    </ul>
    <ul class="date">
      <li class="none-week dayli"  v-for="o in lastMonthDays" :key="o + 50">
        {
   
   { lastMonthStartDay + o - 1 }}
      </li>
      <!-- 当月 -->
      <span
        @click="clickEvent"
        v-for="day in nowMonthDays"
        :key="day"
        :class="day == nowDate.date ? 'dayli today' : 'dayli'"
      >
        {
   
   { day }}
      </span>

      <li
        
        class="none-week dayli"
        v-for="day in 42 - lastMonthDays - nowMonthDays"
        :key="day + 100"
      >
        {

2. Time selection style customization

 Because the time selector el-date-picker of element-UI mounts the element directly in the page <body>, not under its own element, so  the element cannot be located by penetration such as /deep/、 >>>、 ::v-deep  .

solution:

Use the properties of the time picker popper-classto set the style.

There are 2 ways:

1. Create style.scss, write the style in this file, and then import
2. Add style writing in APP.vue (root file)

        <el-date-picker
          type="month"
          popper-class="dark_form" >
        </el-date-picker>

//效果图对应样式



//   日期选择弹窗样式
  .el-picker__popper.el-popper[role="tooltip"] {
    border-color: #24386000;
  }
  .el-popper.is-light .el-popper__arrow::before {
    background: #131e34;
    border: none !important;
  }
  .dark_form {
    background: #131e34 !important;
    border: #131e34;
    .el-date-picker__header--bordered {
      border-bottom: solid 0.01rem #818ea9;
    }
    .el-picker__popper.el-popper[role="tooltip"] .el-popper__arrow::before {
      border: none !important;
    }
    .el-picker-panel__body {
      background: #131e34 !important;
    }
    .el-date-picker__header-label {
      color: #fbfbfb;
      font-family: "HarmonyOS Sans";
    }
    .el-picker-panel__icon-btn {
      color: #fbfbfb;
      font-family: "HarmonyOS Sans";
    }
    .el-month-table td .cell {
      color: #fbfbfb;
      font-family: "HarmonyOS Sans";
    }
	.el-year-table td .cell {
      color: #fbfbfb;
      font-family: "HarmonyOS Sans";
}
  }
