我正在尝试将页面中的html元素对齐一行。
演示： http://plnkr.co/edit/ulLyUxj9C9PxxvpTnm3N?p=preview
在演示中，单击右侧的"在单独的窗口中启动窗口"图标时，将打开一个单独的窗口，其中显示表单元素(未在一行中对齐(。 我希望两个文本元素和提交按钮在同一行上，但对于演示代码，提交和重置按钮与 文本字段。 下面是示例代码：
<div class="col-sm-10">
<div class="">
<div class="row"><div class="form-group col-md-2">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email" placeholder="Enter email" name="email" style="width:130px">
</div>
<div class="form-group col-md-2">
<label for="pwd">Password:</label>
<input type="password" class="form-control" id="pwd" placeholder="Enter password" name="pwd" style="width:130px">
</div>
<button type="submit" class="btn-primary">Submit</button>
<button type="submit" class="btn-primary">Reset</button>
</div>
</div>
</div>
</div>
您可以通过在行div中添加class="form-inline"来解决此问题，例如：
<div class="col-sm-10">
<div class="form-inline">
<div class="row"><div class="form-group col-md-2">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email" placeholder="Enter email" name="email" style="width:130px">
</div>
<div class="form-group col-md-2">
<label for="pwd">Password:</label>
<input type="password" class="form-control" id="pwd" placeholder="Enter password" name="pwd" style="width:130px">
</div>
<button type="submit" class="btn-primary">Submit</button>
<button type="submit" class="btn-primary">Reset</button>
</div>

我在这里做了几件事：
将 btn 类添加到按钮中，以便它们与文本字段具有相同的高度。
我添加了一个空标签，该标签仅在中等断点或更大断点处显示，以填充垂直空间。
包装的按钮位于自己的div 中(因为标签是内联的(
将空标签和新div 包装在他们自己的div.form-group.col 中
<div>
<div class="col-sm-10">
<div class="">
<div class="row">
<div class="form-group col-md-2">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email" placeholder="Enter email" name="email" style="width:130px">
</div>
<div class="form-group col-md-2">
<label for="pwd">Password:</label>
<input type="password" class="form-control" id="pwd" placeholder="Enter password" name="pwd" style="width:130px">
</div>
<div class="form-group col">
<label class="visible-md visible-lg"> </label>
<div>
<button type="submit" class="btn btn-primary">Submit</button>
<button type="submit" class="btn btn-primary">Reset</button>
</div>
</div>
</div>
</div>
</div>
</div>
将类form-control引导程序添加到两个按钮，并在两个按钮之间添加一些边距，使其看起来有点美观。
<button type="submit" class="btn-primary form-control">Submit</button>
<button type="submit" class="btn-primary form-control">Reset</button>
这只是引导网格类问题。
确保包装col's(即。<div class="col-md-2">(与row类。
