Question

我想让边框在整个页面中保持一致。您认为最好的方法是什么？我在下面添加了一个图像，我想到的是将红色区域留空，切割菜单边框以及两侧的所有其余部分，使其全部看起来对齐并居中。谢谢你们。

Answer 1

执行此操作的最佳方法是将内容包装在容器中，并为此设置最大宽度（70％）左右，然后如果要为此容器添加边框，则可以执行此操作。 / p>

添加<div class="container"＆gt;在您想要居中/包含的任何内容之前，然后在结尾处关闭div，并将以下内容添加到您的CSS中：

.container {
  max-width: 70%;
  margin-left: auto;
  margin-right: auto;
}

Answer 2

将您的页面包裹在

中

<div id="wrapper">
    your content here
</div>


/* add this to css */
#wrapper {
    width:960px; /*put here the width you want*/
    margin: 0 auto;
}
/*-----*/
