Here is a fiddle for you: http://jsfiddle.net/maniator/J9bjm/
这是给你的小提琴：http: //jsfiddle.net/maniator/J9bjm/
The only thing you need to grasp from it is the position: absolute;and the top: 0;(or however far away from the top of the page that you want it)
您唯一需要从中掌握的是position: absolute;和top: 0;（或离您想要的页面顶部有多远）

The first answer seems good to me, but here is a link to the w3schools css positionpage. The "try it yourself" is a convenient sandbox.
第一个答案对我来说似乎不错，但这里有一个指向w3schools css 位置页面的链接。“自己尝试”是一个方便的沙箱。
Edit: as noted in the comment, w3schools is not a good reference. I marked the link with strikethrough, but left it live.
编辑：如评论中所述，w3schools 不是一个好的参考。我用删除线标记了链接，但让它保持活动状态。

Here's another solution that might work in your particular case, using negative margin instad of position:
这是另一种可能适用于您的特定情况的解决方案，使用负保证金 instad 位置：
<div id="one">One</div>
<div id="two">Two</div>
#one, #two, #three, #four {
background: #ddd;
height: 100px;
width: 100px;
}
#two {
background: #aaa;
margin-left: 10px; /* Set to 0 for complete overlap */
margin-top: -80px; /* Set to -100 for complete overlap */
}

Depending on the structure of your HTML, you probably don't even need jquery to do this. If you know exactly where you want them to be in the window you can use the position: absolute;CSS on them both. This pageexplains pretty well how to use the positionCSS attribute in different ways to position divs pretty much however you may like.
根据 HTML 的结构，您可能甚至不需要 jquery 来执行此操作。如果您确切地知道希望它们在窗口中的哪个位置，则可以position: absolute;对它们都使用CSS。这个页面很好地解释了如何以position不同的方式使用CSS 属性来定位 div，但是你可能喜欢。
EDIT: I edited the fiddle with
编辑：我编辑了小提琴
body{
padding:0px;
}
To make them line up at the top, the window by default has some padding which affects anything that's not on position: absolute;
为了使它们在顶部排列，默认情况下窗口有一些填充，它会影响任何未打开的内容 position: absolute;
