css web页面实现一个弹窗

2023-10-27

div 基本层级:

    <div class="pc-invest-join-container">
      <div class="bg-wrap">
        <div class="place-hold"></div>
        <div class="top-container">
          <div class="btn-con" @click="openHandle()">点击申请 </div>
        </div>
        <div class="bot-container">
          <div class="btn-con" @click="openHandle()"> 点击申请 </div>
        </div>
   		<!-- 弹窗 -->
        <div class="pc-join-modal-container" v-if="isDlgShow">
          <div class="dialog-wrapper">
          </div>
        </div>
      </div>
    </div>
