输入组与表单组不能很好地工作

Question

我有由angularJS加载的模板，它的超文本标记语言看起来像这样。

<div class="row">
    <div class="col-md-offset-3 col-md-6">

        <div class="panel panel-default">
            <div class="panel-heading">
                <p class="panel-title">Project Detail - {{Name}}</p>
            </div>
            <div class="panel-body">
                <form class="form-horizontal">
                    <div class="form-group">
                        <label for="inputEmail3" class="col-sm-2 control-label">Name</label>
                        <div class="col-sm-10">
                            <input type="text" class="form-control" ng-model="Name" />
                        </div>
                    </div>
                    <div class="form-group">
                        <label class="col-sm-2 control-label" for="Descriptiion">Description</label>
                        <div class="col-sm-10">
                            <textarea class="form-control" ng-model="Description" rows="3"></textarea>
                        </div>
                    </div>
                    <div class="form-group">
                        <label class="col-sm-2 control-label">Start Date</label>
                        <div class="col-sm-10">
                            <div class="input-group" id="startDate">
                                <input type="text" class="form-control"  name="startDate" />
                                <span class="input-group-addon">
                                    <span class="glyphicon glyphicon-calendar">
                                    </span>
                                </span>
                            </div>
                        </div>
                    </div>

                    <div class="form-group">
                        <div class="col-sm-offset-2 col-sm-10">
                            <button type="submit" ng-disabled="myForm.Name.$invalid" class="btn btn-default">Submit</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</div>

输出如下图所示

控件和广告图标之间存在差距。尽管我使用的是col sm-10类，但在控件的右侧也有很多空格。

尝试从cdn关注css，它工作正常
