目标是拥有一个包含两列的表单。在计算机显示器上查看时，会出现两列，但在移动设备上，这些列会堆叠在一起。我正在使用 Bootstrap 。我预计我将使用内联和内联 block 的某种组合，但可以使用一些指导。
示例表格
<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

<title>Test Form</title>
</head>
<style>
/* ??? */
</style>
<body>
<form action="test.php" method="post" enctype="multipart/form-data">
<div class="row">
<div class="form-group col-md-6">

<input type="text" name="value1" class="form-control">
