效果图

 实现代码

<template>
  <el-dialog class="no-code-dialog" v-model="isShow" title="没有收到验证码？">
    <div class="nocode-body">
      <div class="tips">请尝试一下操作</div>
      <div class="wrap">
        <div class="row"><i></i><span>请确认邮箱地址是否输入正确。</span></div>
        <div class="row">
          <i></i><span>邮件发送可能存在延迟，请稍等片刻。</span>
        </div>
        <div class="row"><i></i><span>请确认邮件是否在垃圾箱中。</span></div>
        <div class="row">
          <i></i><span>若问题仍未解决，请联系客服寻求帮助 。</span>
        </div>
      </div>
    </div>
    <template #footer>
      <div class="dialog-btn" @click="isShow = false">确定</div>
    </template>
  </el-dialog>
</template>

<script setup>
import { ref, computed, defineProps, defineEmits } from 'vue';
const props = defineProps({
  modelValue: {
    type: Boolean,
    default: false
  }
});
const emits = defineEmits(['update:modelValue']);
const isShow = computed({
  set(val) {
    emits('update:modelValue', val);
  },
  get() {
    return props.modelValue;
  }
});
</script>

样式修改

<style lang="less" scoped>
.no-code-dialog {
  .nocode-body {
    .tips {
      color: #6c6c6c;
      font-family: PingFang SC;
      font-size: 14px;
      font-weight: 600;
      padding: 30px 0 15px;
    }
    .wrap {
      .row {
        display: flex;
        align-items: center;
        margin-bottom: 10px;
        i {
          display: inline-block;
          width: 7px;
          height: 7px;
          transform: rotate(45deg);
          background-color: #000;
        }
        span {
          color: #000;
          font-family: PingFang SC;
          font-size: 14px;
          margin-left: 10px;
        }
      }
    }
  }
  .dialog-btn {
    display: flex;
    justify-content: center;
    align-items: center;
    width: 372px;
    height: 40px;
    border-radius: 4px;
    background: #000;
    color: #fff;
    font-family: PingFang SC;
    font-size: 14px;
    font-weight: 500;
  }
}
// :deep(.el-dialog) {
//   background: #fff;
// }
// :deep(.el-dialog__body) {
//   height: 350px;
//   padding-bottom: 0px;
// }
</style>
<style lang="less">
.el-overlay {
  .el-overlay-dialog {
    .el-dialog.no-code-dialog {
      --el-dialog-width: 420px;
      --el-dialog-bg-color: #fff;
      .el-dialog__header .el-dialog__title {
        color: #000;
      }
    }
  }
}
</style>

.el-dialog.no-code-dialog 添加自己定义的类名用于区分其他组件

 使用

<template>
  <NoCodeDialog v-model="isShowNoCodeDialog" />
  <SuccessDialog v-model="isSuccessDialog" />
</template>

<script setup>
import { ref } from 'vue';
import NoCodeDialog from '@/views/Register/components/NoCodeDialog.vue';
import SuccessDialog from '@/views/Register/components/SuccessDialog.vue';
const isShowNoCodeDialog = ref(true);
const isSuccessDialog = ref(true);
</script>
