尝试将其添加到您的css中：

Try adding this to your css:

.fb_edge_comment_widget {
    margin-left: -350px;
}

这将向左移动注释框，但指向按钮也将移动（您可以尝试用另一个元素覆盖）。如果您使用XFBML，而不是iframe，它将会工作。

This will move comment box to the left, but the little arrow pointing to the button will move too (which you could try to cover with another element). It will only work if you're using XFBML, not an iframe.

以下是示例。
