边框由标题和主体两部分组成。背景采用类似九宫格方式切图，适应大部分宽高而不变形。

组件代码

组件包含了三部分：标题 主体 背景。

标题使用的是vue3 数据可视化大屏标题组件-数据资产

主体部分放了一个插槽，通过插槽将其他组件插入到当前组件中。

<template>
  <div class="pageItemBody">
    <itemTitle :title="title"></itemTitle>
    <div class="itemMain">
      <slot></slot>
      <bg></bg>
    </div>
  </div>
</template>

<script>
import itemTitle from "./itemTitle/index.vue";
import bg from './bg.vue'
export default {
  name: "title",
  data() {
    return {}
  },
  components: {
    itemTitle,
    bg
  },
  props: {
    title: {
      type: String,
      default() {
        return '标题';
      }
    },
  },
  watch: {},
  mounted() {
    var that = this;
  },
}
</script>

<style lang="scss" scoped>
.pageItemBody {
  width: 100%;
  position: relative;
  height: 100%;
  display: flex;
  justify-content: flex-start;
  align-items: flex-start;
  flex-wrap: nowrap;
  flex-direction: column;
  z-index: 1;
  align-content: flex-start;
}

.itemMain {
  position: relative;
  width: 100%;
  height: calc(100% - 60px);
}
</style>

背景组件

背景图因为有一些装饰的地方不能够无限拉伸宽高，为了能够在不同宽高的区域使用，这里做了类似九宫格的处理。
