标签:对齐 必须 btn NPU col 100% str trap control
基本实例:
from-group:可以是其内的标签排列更好
from-control:使标签宽度为100%
<form> <div class="form-group"> <label for="exampleInputEmail1">Email address</label> <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Email"> </div> <div class="form-group"> <label for="exampleInputPassword1">Password</label> <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password"> </div> <div class="form-group"> <label for="exampleInputFile">File input</label> <input type="file" id="exampleInputFile"> <p class="help-block">Example block-level help text here.</p> </div> <div class="checkbox"> <label> <input type="checkbox"> Check me out </label> </div> <button type="submit" class="btn btn-default">Submit</button> </form>
form-inline: 其内标签水平排列
.form-inline
类可使其内容左对齐并且表现为 inline-block
级别的控件。只适用于视口(viewport)至少在 768px 宽度时(视口宽度再小的话就会使表单折叠)。
必须有label标签:如果不限让label显示。可以设置 .sr-only
<form class="form-inline"> <div class="form-group"> <label for="exampleInputName2">Name</label> <input type="text" class="form-control" id="exampleInputName2" placeholder="Jane Doe"> </div> <div class="form-group"> <label for="exampleInputEmail2">Email</label> <input type="email" class="form-control" id="exampleInputEmail2" placeholder="jane.doe@example.com"> </div> <button type="submit" class="btn btn-default">Send invitation</button> </form>
通过为表单添加 .form-horizontal
类,并联合使用 Bootstrap 预置的栅格类,可以将 label
标签和控件组水平并排布局。这样做将改变 .form-group
的行为,使其表现为栅格系统中的行(row),因此就无需再额外添加 .row
了。
将每一个 .form-group水平排列
control-label:将label和div 水平排列整齐
<form class="form-horizontal"> <div class="form-group"> <label for="inputEmail3" class="col-sm-2 control-label">Email</label> <div class="col-sm-10"> <input type="email" class="form-control" id="inputEmail3" placeholder="Email"> </div> </div> <div class="form-group"> <label for="inputPassword3" class="col-sm-2 control-label">Password</label> <div class="col-sm-10"> <input type="password" class="form-control" id="inputPassword3" placeholder="Password"> </div> </div> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <div class="checkbox"> <label> <input type="checkbox"> Remember me </label> </div> </div> </div> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <button type="submit" class="btn btn-default">Sign in</button> </div> </div> </form>
