我试图设计一个引导表单，其中第一行有1个输入，第二行有2个输入。这是一张不起作用的照片，你可以看到我在做什么…
噢，我多么希望那些男孩能排得整齐！我已经盯着这个看太久了-感觉像是保证金问题，但我可能只是错过了一些明显的东西。
有人能发现我的错误吗？我把它归结为赤裸裸的：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>
<div class="container body-content"><br><br>
<form>
<div class="form-horizontal row">
<div class="form-group col-sm-12">
<label class="control-label col-sm-2">Supplier</label>
<div class="col-sm-10">
<input class="form-control"/>
</div>
</div>
<div class="row">
<div class="form-group col-sm-6">
<label class="control-label col-sm-4">Contact</label>
<div class="col-sm-8">
<input class="form-control"/>
</div>
</div>
<div class="form-group col-sm-6">
<label class="control-label col-sm-4">Phone</label>
<div class="col-sm-8">
<input class="form-control"/>
</div>
</div>
</div>
</div>
</form>
</div>
</body>
</html>
希望你能帮忙！
最佳答案
不要对表单控件应用列数，而是用所需列数将所有控件包装在<div>'s中：
<div class="container body-content"><br><br>
<form>
<div class="form-horizontal">
<div class="col-sm-12">
<div class="form-group">
<label class="control-label col-sm-2">Supplier</label>
<div class="col-sm-10">
<input class="form-control"/>
</div>
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label class="control-label col-sm-4">Contact</label>
<div class="col-sm-8">
<input class="form-control"/>
</div>
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label class="control-label col-sm-4">Phone</label>
<div class="col-sm-8">
<input class="form-control"/>
</div>
</div>
</div>
</div>
</form>
