我有一个 iframe；
那指向一个 .php 文件
我需要回显的图像在 iframe 中居中。所有图像的宽度均为 960 像素，但 iframe 宽度需要为 100%，因为它并不总是那么宽（它所在的某些页面可能是 600 像素宽）。
任何建议将不胜感激。

1) Padding is only placed on the top and/or bottom of the div. The elements within this
div have padding on their sides. This saves you from any "box model math". Keep in
mind, if you add any side padding or border to the div itself, it will be added to the
width you define to create the *total* width. You may also choose to remove the padding
on the element in the div and place a second div within it with no width and the
padding necessary for your design.
