徽标从页面顶部向下移动。不知道为什么
在我的网站上，某个特定页面的徽标被向下移动了几个像素，而在所有其他页面上却没有。所有页面的代码都是相同的（至少我认为是），所以我不确定是什么导致了问题。
以下是工作与非工作的屏幕截图：

两者的代码如下所示，但由于某种原因，其中一个页面无法正确呈现
<body>

这是生成的 html工作：
这是不工作的：
On my site for one particular page the logo is nudged down a few pixels, while on all the other pages it is not. The code is identical(at least I think it is) for all pages so I'm not sure what is causing the issue.
Here is a screen shot of a working vs non working:

Non-Working:
The code for both is shown below however for some reason, one of the pages doesn't render correctly

对于 css 目的 IE7 与 IE8 不同，并且它们都与 FIREFOX、CHROME 不同......
我没有看到您使用为 IE7 指定 css 文件
您需要在页面中为 IE7 提供备用 css
for css purpose IE7 different from IE8 and they all differnet from FIREFOX, CHROME....
I dont see you specifying css file for IE7 using
You need to have alternate css for IE7 in your page
