优化这个布局<view class="box"> <uni-row class="demo-uni-row"> <uni-col :span="12"> <view class="boxnormal"> <text class="normaltext">正常气罐\n</text> <text class="normalSize">{{normalNumber}}</text> </view> </uni-col> <uni-col :span="12"> <view> <view class="warning"> <text class="warningtext">预警</text> <text class="warningSize">{{warningNumber}}</text> </view> <view class="error"> <text class="errortext">警告</text> <text class="errorSize">{{errorNumber}}</text> </view> </view> </uni-col> </uni-row> </view>

可以通过以下方式对这个布局进行优化：

1. 使用flex布局代替uni-row和uni-col布局，可以减少代码量，提高布局效率。

<view class="box">
  <view class="boxnormal">
    <text class="normaltext">正常气罐</text>
    <text class="normalSize">{{normalNumber}}</text>
  </view>
  <view class="warning">
    <text class="warningtext">预警</text>
    <text class="warningSize">{{warningNumber}}</text>
  </view>
  <view class="error">
    <text class="errortext">警告</text>
    <text class="errorSize">{{errorNumber}}</text>
  </view>
</view>

.box {
  display: flex;
  justify-content: space-between;
}

.boxnormal {
  display: flex;
  flex-direction: column;
  align-items: center;
}

.warning, .error {
  display: flex;
  flex-direction: column;
  align-items: center;
}

.warning {
  background-color: #f5a623;
}

.error {
  background-color: #f44336;
}

2. 将重复的样式封装成class，减少重复代码。

<view class="box">
  <view class="boxnormal normal">
    <text class="normaltext">正常气罐</text>
    <text class="normalSize">{{normalNumber}}</text>
  </view>
  <view class="warning normalSize warningSize">预警 {{warningNumber}}</view>
  <view class="error normalSize errorSize">警告 {{errorNumber}}</view>
</view>

.box {
  display: flex;
  justify-content: space-between;
}

.normal {
  display: flex;
  flex-direction: column;
  align-items: center;
}

.warning {
  background-color: #f5a623;
}

.error {
  background-color: #f44336;
}
