bootstrap css样式之表单
人气:0本文实例为大家分享了bootstrap表单的具体代码,供大家参考,具体内容如下
1、表单基本用法
<form role="form"> <div class="form-group"> <label for="exampleInputEmail1">Email address</label> <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter 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>
2、内联表单
为 form 元素添加 .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)。
一定要添加 label 标签
如果你没有为每个输入控件设置 label 标签,屏幕阅读器将无法正确识别。对于这些内联表单,你可以通过为 label 设置 .sr-only 类将其隐藏。
<form class="form-inline" role="form"> <div class="form-group"> <label class="sr-only" for="exampleInputEmail2">Email address</label> <input type="email" class="form-control" id="exampleInputEmail2" placeholder="Enter email"> </div> <div class="form-group"> <div class="input-group"> <div class="input-group-addon">@</div> <input class="form-control" type="email" placeholder="Enter email"> </div> </div> <div class="form-group"> <label class="sr-only" for="exampleInputPassword2">Password</label> <input type="password" class="form-control" id="exampleInputPassword2" placeholder="Password"> </div> <div class="checkbox"> <label> <input type="checkbox"> Remember me </label> </div> <button type="submit" class="btn btn-default">Sign in</button> </form>
3、水平排列的表单
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。
<form class="form-horizontal" role="form"> <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>
