表单控件中的Bootstrap输入文本占用了一些不必要的边距

Question

我想使用bootstrap创建一个表单。 当试图创建它时，在输入的右侧给出了不必要的边距。我试图检查浏览器控制台中的边距。这可能是一件小事，但无法弄清楚。我也附了一个屏幕截图。

   <div class="col-lg-8 col-md-8 col-sm-12">
            <div class="panel panel-default">
                <div class="panel-body">
                    <div id="tenantForm" class="container">
                        <center> <h4>Login Form</h4></center>
                        <hr />

                        <form>
                            <div class="form-group">
                                <label for="email">Email address:</label>
                                <input type="email" class="form-control" id="email">
                            </div>
                            <div class="form-group">
                                <label for="pwd">Password:</label>
                                <input type="password" class="form-control" id="pwd">
                            </div>
                            <div class="checkbox">
                                <label><input type="checkbox"> Remember me</label>
                            </div>
                            <button type="submit" class="btn btn-default">Submit</button>
                        </form>
                    </div>
             </div>
    </div>
<div>

从container

    <div class="panel-body">
      <div id="tenantForm">
        <center>
          <h4>Login Form</h4>
        </center>
        <hr />

        <form>
          <div class="form-group">
            <label for="email">Email address:</label>
            <input type="email" class="form-control" id="email">

          <div class="checkbox">
            <label><input type="checkbox"> Remember me</label>
          </div>
          <button type="submit" class="btn btn-default">Submit</button>
        </form>
