I have a problem which points to CSS 3. Please see the part of my HTML code:
我有一个指向 CSS 3 的问题。请查看我的 HTML 代码部分：
<div id="main" style="width: 320px; height: 400px;">
<img src="test.jpg" height="400" />
</div>
I don't know the real sizes of the test.jpg file (width can be different - the file is dynamic). I want to have the image in the middle of id="main" (I don't care, that the left & right part of the image will be out of range - it's even better). How can I do that ?
我不知道 test.jpg 文件的实际大小（宽度可以不同 - 文件是动态的）。我想在 id="main" 中间放置图像（我不在乎，图像的左右部分会超出范围 - 甚至更好）。我怎样才能做到这一点 ？

As long as you specify any width, you can center by adding margin:auto;. This isn't CSS3.
只要指定 any width，就可以通过添加margin:auto;. 这不是 CSS3。
<img src="test.jpg" style="margin:auto; width:200px;display:block" />

this will do the work
这将完成工作
<div id="main" style="width: 320px; height: 400px;background-position:center;background-repeat:no-repeat;background-image:url('test.jpg')">
</div>
