我正在使用 Twitter 的 Bootstrap 构建一个表单(由 django 提供)。我想让表单居中显示在页面上,但我遇到了一些问题。

这是我的 HTML:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My Form</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="description" content="">
<meta name="author" content="">

<!-- Le styles -->
<link href="/bootstrap/css/bootstrap.css" rel="stylesheet">
<style>
body {
padding-top: 60px; /* 60px to make the container go all the way to the bottom of the topbar */
}
</style>
<link href="/bootstrap/css/bootstrap-responsive.css" rel="stylesheet">

<!-- Le HTML5 shim, for IE6-8 support of HTML5 elements -->
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
</head>

<body>
<div class="container">
<div class="row">
<div class="span12" style="text-align:center; margin: 0 auto;">
<form class="form-horizontal" method="post" action="/form/">
<fieldset>
<legend>Please login</legend>
<div class="control-group">
<label class="control-label" for="id_username">Username</label>
<div class="controls">
<input name="username" maxlength="100" placeholder="Enter your username..." type="text" class="input-large" id="id_username" />
</div>
</div>
<div class="control-group">
<label class="control-label" for="id_password">Password</label>
<div class="controls">
<input name="password" maxlength="100" placeholder="Enter your password..." type="password" class="input-large" id="id_password" />
</div>
</div>
</fieldset>
</form>
</div>
</div>
</div>

<!-- Le javascript
================================================== -->
<!-- Placed at the end of the document so the pages load faster -->
<script src="/bootstrap/js/jquery.js"></script>
<script src="/bootstrap/js/bootstrap-transition.js"></script>
<script src="/bootstrap/js/bootstrap-alert.js"></script>
<script src="/bootstrap/js/bootstrap-modal.js"></script>
</body>
</html>

我已经排除了一些额外的 Django 逻辑({% csrf_token %}、一些 if 语句等),但这应该会重现问题。

实际的输入元素(用户名和密码文本框)像我预期的那样居中,但标签仍然在页面的最左边。我是否在某处遗漏了标记,或者我是否必须覆盖某些控制标签 CSS?

最佳答案

您需要将您的表单包含在一个容器中,bootstrap 已经带有一个 width:940px 的容器类,因此您可以将所有内容包装在里面并且它会自动居中,如下所示:

<div class="container">
<div class="row">
<div class="span12">
<form class="form-horizontal" method="post" action="/form/">
<fieldset>
<legend>Please login</legend>
<div class="control-group">
<label class="control-label" for="id_username">Username</label>
<div class="controls">
<input name="username" maxlength="100" placeholder="Enter your username..." type="text" class="input-large" id="id_username" />
</div>
</div>
<div class="control-group">
<label class="control-label" for="id_password">Password</label>
<div class="controls">
<input name="password" maxlength="100" placeholder="Enter your password..." type="password" class="input-large" id="id_password" />
</div>
</div>
</fieldset>
</form>
</div>
</div>
</div>
