php - Bootstrap 表单对齐

Question

好吧，我在表单对齐方面遇到了一些问题。我在 2 个不同的文件上尝试了它，一个给出了正确的对齐方式，另一个没有(这是 codeigniter 的 View )。请帮忙。提前致谢:)

CI View 下的文件及其截图如下

<?php $tab = (isset($_GET['tab'])) ? $_GET['tab'] : 'add-user'; ?>
<div class="container">
   <div class="row" style="margin-top:50px;">

Bootstrap form with proper alignment

Answer 1

尝试将类“行”添加到每个 <div class="form-group"> . IIRC 来自 bootstrap，col 类在行容器中工作得更好。
