Question

我正在为我的高中机器人团队开发一个网站，我想像其他网页一样为这一页创建边距，但是当我将边距设置为自动或任何有价值时，它什么也没做。我正在使用bootstrap。

页面我想要利润 - http://www.robotichive3774.com/Our%20Coach/

Answer 1

将您想要位于页面中间的代码（即带边距）包装在容器中：

<div class="container">
    your code in here...
</div>

引导程序中的容器是使内容位于页面中间的部分

您可以在打开的身体标签后直接放置容器的开口，然后在

之前关闭div

如何像其他页面一样在此页面上获得边距？
