CSS:在y轴上集中元素的标准(动态)方式 [英] CSS: Standard (dynamic) way to centralize an element in the y-axis
问题描述
我的问题或多或少是不言自明的,我试图找到一个标准的动态方式来集中一个元素在y轴,很像:
my question is more or less self-explanatory, I am trying to find a standard dynamic way to centralize an element in the y-axis, much like the:
margin: auto;
对于x轴。任何想法?
我说的是下面这段代码,空白页,在中心对齐一张图片。
I am talking about the following piece of code, empty page, align one image in the center.
<div id="main" style="display: block;">
<img style="margin: auto; display: block;"
src="http://www.example.com/img.jpg" />
</div>
任何帮助将不胜感激! :)
Any help will be appreciated! :)
推荐答案
只要放弃并使用这个表, vertical-align:middle
。你可以逃离只有一行,单细胞表,没有感觉太内疚(我睡得像一个婴儿)。它不是世界上最语义的东西,但你宁愿保持什么,一个小单元格的桌子,或者弄清楚确切的高度,做负绝对定位?
Just give up and use tables on this one, with vertical-align: middle
. You can get away with just a single-row, single-cell table without feeling too guilty (I sleep like a baby about it). It's not the most semantic thing in the world, but what would you rather maintain, a tiny one celled table, or figuring out the exact height and doing absolute positioning with negative margins?
