如果您使用内部样式表
<head>
<style>
.border-class
{
border:thin black solid;
margin:20px;
padding:20px;
}
</style>
</head>
<body>
<div class="d-flex justify-content-center ">
<form class="border-class">
<div class="form-group row">
<div class="col-sm-12">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
<div class="form-group row">
<div class="col-sm-12">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
<div class="form-group row">
<div class=" col-sm-12">
<button type="submit" class="btn btn-primary">Sign in</button>
</div>
</div>
</form>
</div>
</body>

是的,您可以在表单周围放置边框。你可以通过使用内联CSS实现这一点,如下所示:
<form style="border:1px solid black">

在您的外部div元素中添加“ well”标签
Ex:

我知道这是一个很晚的回应,但是我有义务分享一种更“引导”的方式。只需将card
和p-1
类用于边界和内容与边界之间的填充。
<form class = 'card p-1'>
答案 5 :(得分:0)
这是带有背景颜色的边框形式的很好的组合:
<form class = 'card p-3 bg-light'>
对我的情况很好。
