集中在容器中

Question

我有一个页面，我已从页面中取出一些元素以使其符合我的目的（关于页面）但是，我似乎没有看到CSS在哪里可以将容器集中到页面中间。我尝试过做位置：中心以及我在网上阅读的其他代码技术但是他们似乎都想工作。

有人能告诉我我犯了哪些错误。

Answer 1

没有像position:center;这样的东西，你想要做的是为容器定义静态宽度，然后使用margin:0 auto;来居中它。

.container {
  width:600px;
  height:500px;
  background:black;
  margin:0 auto; /* this will center the container */
}

<div class="container"></div>

Answer 2

给出固定宽度并应用保证金：0 auto;

人们总是问如何集中我喜欢的东西来引用这篇名为How to center things from W3C的帖子。有用的信息如果您想了解一下。
