问题描述
所以,基本上最后一次我做过任何网页开发,只有HTML,我没有超过一个基本的了解。所以现在,我正在赶上,试图学习CSS。我的问题是水平导航栏,它不会保持完全居中。我已经尝试调整宽度,边框和边距,但我错过了一些东西。
So, essentially the last time I ever did any web-page development, there was only HTML, and I didn't have anymore than a basic understanding anyways. So now, I'm playing catch up and trying to learn CSS. My issue is a horizontal navbar, which doesn't stay perfectly centered. I've tried adjusting widths, and borders, and margins but I'm missing something.
在我的当前布局,左边有一些空格
With my current layout, there is a tad more whitespace on the left than the right, and I am stuck.

推荐答案
您需要一个固定宽度+ margin-left:auto
和
margin-right:auto
。您不应该对自己的内容使用绝对定位 - 让它自然流动。
You need a fixed width + margin-left:auto
and margin-right:auto
. You should not be using absolute positioning for your content - let it flow naturally.
< center>
标记已被弃用,因此对于宽度为960像素的外部容器包装程序使用相同的技术;。
The <center>
tag has been deprecated, so use the same technique for your outer "container" wrapper with a width of 960px;.
ul {
width:500px;
list-style-type: none;
margin-left:auto;
margin-right:auto;
padding:0;
}
一般来说,使用基于列表的菜单时,使用 float:left
,在A标签上使用 display:block
,将所有其他样式放在A标签上,而不是列表
In general when using list-based menus, use float:left
on your LI, use display:block
on the A-tag and put all other styling on the A-tag, not the list itself.
