Bootstrap 5 在导航栏中对齐项目

Question

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">

  <%= link_to "My Ozone", root_path, class: "navbar-brand" %>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse justify-content-end" id="navbarSupportedContent">
    <%= form_tag zipcode_path, :method => 'POST' do %>
    <div class="form-inline my-2 my-lg-0">
      <%= text_field_tag 'zipcode', nil, placeholder: "Search Zipcode", class: "form-control mr-sm-2" %>
      <%= submit_tag 'Search', class: 'btn btn-outline-secondary my-2 my-sm-0' %>
    </div>
    <% end %>
  </div>
</nav>

我已经在 Rails 项目上完成了一个 Ruby，该项目根据搜索的邮政编码显示臭氧信息。但是，我似乎无法获得彼此相邻的字段和提交按钮。我尝试了各种不同的方法，例如更改 div class 并将内容包装在表单标记中，但似乎无法解决问题。寻求有关使项目在同一行对齐的帮助。

您需要在 Bootstrap 中使用 d-flex 而不是 form-inline class 5.

Dropped form-specific layout classes for our grid system in Bootstrap 5. Use our grid and utilities instead of .form-group, .form-row, or .form-inline - more details here

您的代码应如下所示：

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">

  <%= link_to "My Ozone", root_path, class: "navbar-brand" %>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse justify-content-end" id="navbarSupportedContent">
    <%= form_tag zipcode_path, :method => 'POST' do %>
    <div class="d-flex my-2 my-lg-0">
      <%= text_field_tag 'zipcode', nil, placeholder: "Search Zipcode", class: "form-control mr-sm-2" %>
      <%= submit_tag 'Search', class: 'btn btn-outline-secondary my-2 my-sm-0' %>
    </div>
    <% end %>
  </div>
</nav>
