css - Bootstrap 登录表单重叠

Question

我想创建不同的登录表单。我如何将我的登录容器放在一起？我尝试调整列网格，但没有用。我尝试向每个登录容器添加 col-sm-12 和 col-sm-6。

<div class="container">
<div class="row">
<div class="col-sm-6">
<div class="login-container">
        <div id="output"></div>
            <div class="avatar"></div>
                <div class="form-box">
                    <form accept-charset="UTF-8" role="form" class="form-signin" action="login2.php" method="post">
                        <input class="form-control" placeholder="Username" name="username" type="text">
                        <input class="form-control" placeholder="Password" name="password" type="password">
                        <button class="btn btn-info btn-block login" type="submit" name="login" id="login">Login</button>
                    </form>
                </div>
            </div>
        </div>
 </div>
 </div>
 </div>
<div class="col-sm-6">
<div class="login-container">
        <div id="output"></div>
            <div class="avatar"></div>
                <div class="form-box">
                    <form accept-charset="UTF-8" role="form" class="form-signin" action="login2.php" method="post">
                        <input class="form-control" placeholder="Username" name="username" type="text">
                        <input class="form-control" placeholder="Password" name="password" type="password">
                        <button class="btn btn-info btn-block login" type="submit" name="login" id="login">Login</button>
                    </form>
                </div>
            </div>
        </div>
 </div>
 </div>
</div>

Answer 1

您需要调整您的 HTML 结构。当前，在您到达第二个 col-sm-6 之前，您第一个 col-sm-6 在容器和行中关闭。两列都应位于 container 和 row 内。参见 Grid System .

参见示例代码段。

/**FOR DEMO ONLY**/

body {
  padding-top: 50px;
}
.login-container {
  background: #f2f2f2;
  padding: 20px 15px 5px;
}
/**FOR DEMO ONLY**/

@media (max-width: 767px) {
  .no-gutter > [class*='col-'] {
    padding-right: 0;
    padding-left: 0;
  }
}

<div class="container">
  <h3>Stacks @ Under 768px</h3>
  <div class="row">
    <div class="col-sm-6">
      <div class="login-container">
        <div id="output"></div>
        <div class="avatar"></div>

        <form accept-charset="UTF-8" role="form" class="form-signin" action="login2.php" method="post">
          <div class="form-group">
            <input class="form-control" placeholder="Username" name="username" type="text">
          </div>
          <div class="form-group">
            <input class="form-control" placeholder="Password" name="password" type="password">
          </div>
          <div class="form-group">
            <button class="btn btn-info btn-block login" type="submit" name="login" id="login">Login</button>
          </div>
        </form>

      </div>

    <div class="col-sm-6">
      <div class="login-container">
        <div id="output"></div>
        <div class="avatar"></div>
