我在iPhone和iPad上查看网站时遇到了一些困难。尽管网站还远没有完成，但是在我使用的每个桌面浏览器上（如safari、chrome、firefox、IE）都能正常显示。然而，在iPhone/iPad上，"内容" div、页眉和页脚之间存在微小的间隙/空白。我在页眉、内容和页脚 div 中使用背景图像来创建页面的轮廓。除了 div 之间的间隙之外，内容背景图像有时会被“缩小”一点，以致于它不能与屏幕右侧的页眉和页脚对齐。但如果我放大屏幕，一切都会完美地对齐。这是从iPhone上拍摄的屏幕截图...
仔细看右侧蓝色导航栏下面。
这是 CSS（我知道它非常粗糙，我正在学习）。

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.

有人知道为什么iPhone和iPad会以这种方式渲染页面吗？
