推荐答案

我明白了！我必须承认，这是一个非常奇怪的故事.

I got it! I must admit, this was a very strange one.

This was my exact problem, and his solution fixed it perfectly.

问题是由于include().

The problem was because of the include().

将页面另存为UTF-8时，文件的开头会包含一个称为字节顺序标记(或BOM)的特殊签名，表明它是UTF-8文件.您只能使用低级文本编辑器(例如 DOS修改).您需要从包含的文件中删除此签名，以便摆脱页面顶部的空白.

When you save a page as UTF-8, a special signature called a byte-order mark (or BOM) is included at the beginning of the file, indicating that it is a UTF-8 file. You can only see BOMs with low level text editors (such as DOS edit). You need to remove this signature from the included file in order to get rid of the white space at the top of the page.
