如何使元素在左侧对齐响应

Question

当我尝试最小化浏览器的 window 时，我试图使元素 'branch' 响应式完全对齐在 'status' 下方，我该怎么做？这是我到目前为止所得到的result，我也尝试使用@media only screen CSS 但仍然没有响应的迹象，这是我的代码行

`

<template>
  <base-header class="pb-4 pb-5 pt-6 pt-md-6 bg-gradient-success">
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1.0, maximum-scale=1"
    />

    <template>
      <div>
        <b-form inline>
          <label for="status">Status⠀⠀⠀⠀ :</label>
          <div class="col-sm-2">
            <b-form-input v-model="text"></b-form-input>
          </div>
          <!-- branchstyle -->
          <div class="branch">
            <div class="col-lg-10 text-right">
              <b-form inline label-align-sm="right" style="margin-left: 70px">
                <div class="col-sm-2" label for="branch">Branch⠀:</div>
                <div class="col-sm-8">
                  <b-form-input
                    v-model="text"
                    style="margin-left: 33px"
                  ></b-form-input>
                </div>
                <br />
                <!-- <div class="input-group col-sm-2">
                  <b-button variant="outline-dark"></b-button>
                </div> -->
                <!-- <div>

          <div class="col-sm-2">
            <b-form-input v-model="text"></b-form-input>
          </div>
          <div class="branch">
            <div class="col-lg-12 text-right">
              <b-form inline label-align-sm="right">
                <div class="input-group col-sm-10">
                  <b-button
                    variant="dark"

我尝试模拟您的问题并实施此代码段。因为我无法在代码片段中看到您的结果，所以我假设您想要一个响应式表单，当屏幕最小化时，您的输入会被放置在正确的部分。

为了提高可读性，我做了一些清理和改进，并且我使用了 flex 来解决您的响应问题。

new Vue({
  el: "#app",
  data: function() {
    return {
      text: "a",
      fields: ['first_name', 'last_name', 'age'],
      items: [{
          isActive: true,
          age: 40,
          first_name: 'Dickerson',
          last_name: 'Macdonald'
        },
        {
          isActive: false,
          age: 21,
          first_name: 'Larsen',
          last_name: 'Shaw'
        },
        {
          isActive: false,
          age: 89,
          first_name: 'Geneva',
          last_name: 'Wilson'
        },
        {
          isActive: true,
          age: 38,
          first_name: 'Jami',
          last_name: 'Carney'
        }
      ]
    }
  },
});

.customForm>div {
  display: flex;
  flex: 1 0 250px;
  margin: 1rem;

}

.customForm {
  display: flex;
  flex-wrap: wrap;
}

.customForm > div > label {
flex: 1 0 auto;
align-items: flex-end;
display: flex;
margin-right: .5rem;
}
