我如何以html格式为中心？

标签： html css

所以我看了这个关于如何创建一个好的联系我表格的教程。但问题是我无法集中精力。它使用一些网格标签，并且响应迅速。所以我想保持响应，但在全宽时我希望它像徽标一样居中。 （HTML和CSS刚刚学习的新手） HTML代码

MessageProperties messageProperties = new MessageProperties();
messageProperties.setHeader("color", "red");
MessageConverter messageConverter = new SimpleMessageConverter();
Message message = messageConverter.toMessage("Hello World !", messageProperties);
rabbitTemplate.send("helloworld.header.x", "", message);

我的CSS 

<div class="container">
<h1 class="brand"><span>Acme</span> Web Design</h1>
<div class="wrapper animated bounceInLeft">

  <div class="contact">
    <h3>Email Us</h3>
    <form>
      <p>
        <label>Name</label>
        <input type="text" name="name">
      </p>
      <p>
        <label>Company</label>
        <input type="text" name="company">
      </p>
      <p>
        <label>Email Address</label>
        <input type="email" name="email">

      <p class="full">

        <textarea name="message" rows="5"></textarea>

      <p class="full">

虽然您可以使用margin: auto，但如果您使用代码中未显示的网格，可能会发现奇怪的行为。

这段代码可能有所帮助，基本上我已经删除了影响表单容器的代码，并添加了它以便在单个字段中响应。

根据您是否想要将整个块保持为网格格式，您可以随时更改.wrapper以不使用网格，但只有0px auto的边距。如果您仍想使用网格布局，则可以将.wrapper更改为宽度为100％
