el-popover修改样式

el-popover的样式可以通过设置全局样式或者使用popper-class属性来修改。在App.vue中添加以下样式可以修改el-popover的样式：

.el-popover {
  position: absolute;
  background: rgba(22,38,94,1) !important;
  min-width: 73%;
  width: 100%;
  border: 0px solid #EBEEF5;
  padding: 12px;
  z-index: 2000;
  margin-right: 55px;
  color: white;
  line-height: 1.4;
  text-align: justify;
  font-size: 14px;
  box-shadow: 0 2px 12px 0 rgba(0,0,0,.1);
  word-break: break-all;
}

.el-popper\[x-placement^=top\] .popper__arrow::after {
  bottom: -0.2px;
  margin-left: -6px;
  border-top-color: rgba(22,38,94,1) !important;
}

另外，你也可以在el-popover组件中使用popper-class属性来修改样式。例如：

<el-popover width="300" trigger="hover" popper-class="popperOptions" placement="top-start">
  <!-- 弹出框内容 -->
</el-popover>

然后在样式中定义popperOptions类来修改样式：

.popperOptions\[x-placement^=left\] .popper__arrow::after {
  border-left-color: #EA4E3D;
}

.popperOptions\[x-placement^=right\] .popper__arrow::after {
  border-right-color: #EA4E3D;
}

.popperOptions\[x-placement^=bottom\] .popper__arrow::after {
  border-bottom-color: #EA4E3D;
}

.popperOptions\[x-placement^=top\] .popper__arrow::after {
  border-top-color: #EA4E3D;
}

.popperOptions {
  background-color: #EA4E3D;
  color: #FFFFFF;
  font-size: 18px;
  padding: 5px;
  border: #EA4E3D;
}

这样就可以根据需要修改el-popover的样式了。
