我正在使用bootstrap 3创建选项卡。唯一的问题是第二个选项卡的内容在第一个选项卡顶部添加空间后开始。
在理想情况下，内容上方不应有任何空间

<div class="col-sm-9">
    <ul class="nav nav-tabs nav-justified" role="tablist">
        <li role="presentation" class="active">
            <a href="#uploadFormat" data-toggle="tab">Client Upload Format</a>
        </li>
        <li role="presentation">
            <a href="#upload" data-toggle="tab">Client Bulk Upload</a>
        </li>
    </ul>
    <div class="tab-content">
    <br/>
        <div class="tab pane fade active in" id="uploadFormat">
            <div class="form-bottom">
                <p>saurabh</p>
                <p>saurabh</p>
                <p>saurabh</p>
                <p>saurabh</p>
                <p>saurabh</p>
            </div>
        </div>
        <div class="tab pane fade" id="upload">         
            <form>
            <fieldset>
                <div class="form-group">
                    <label for="client_upload_file">Upload Client File</label>
                    <input type="file" name="client_upload_file" id="client_upload_file"/>
                </div>
                <div class="form-group">
                    <button class="btn btn-primary btn-sm" type="submit" name="clientUpload">Upload Client File</button>
                </div>
            </fieldset>
            </form>
        </div>
    </div>
