iphone - 在 iPhone/iPad 上查看网站上的 div 之间的空间/间隙

Question

在 iPhone 和 iPad 上查看时，我无法正确显示我的网站。网站(甚至还没有完成)是www.lzkconcepts.com。

在我尝试过的每个桌面浏览器(safari、chrome、firefox、IE)上查看时，该网站都能正常显示，但是，在 iPhone/iPad 上，“内容”div 和标题之间存在微小的间隙/空间，并且页脚。我在页眉、内容和页脚 div 中使用背景图像来创建页面轮廓。除了 div 之间的间隙之外，内容背景图像有时会“缩小”一点，因此它不会与屏幕右侧的页眉和页脚对齐。但是，如果我放大，一切都会完美排列。这是从 iPhone 截取的屏幕截图...

仔细观察蓝色导航栏下方的右侧。

这是CSS(我知道它很粗糙，我只是在学习)

@charset "UTF-8";
body {
 margin: 0;
 padding: 0;

 font-family: Arial, Helvetica, sans-serif;

ul, ol, dl { /* Due to variations between browsers, it's best practices to zero padding and margin on lists.

 padding: 0;
 margin: 0;
}
h1, h2, h3, h4, h5, h6, p {
 margin-top: 0;  /* removing the top margin gets around an issue where margins can escape from their containing div. The remaining bottom margin will hold it away from any elements that follow. */
 padding-right: 15px;
 padding-left: 15px; /* adding the padding to the sides of the elements within the divs, instead of the divs themselves, gets rid of any box model math. A nested div with side padding can also be used as an alternate method. */

 border: none;

/* ~~ this fixed width container surrounds the other divs ~~ */
.container {

 height: 165px;
}

/* ~~ This is the layout information. ~~ 

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.

有谁知道为什么 iPhone 和 iPad 会这样呈现页面？

Answer 1

在 iPad 上，当以低于 100% 的比例查看网站时，有时会出现一些伪像。一个特别明显:div 之间的 1 像素线，就像在您的网站上一样，位于菜单下方。

我找到的解决方案是在 div 之间添加一个“边距:-1px”。 Divs 背景重叠 1 个像素，如果相应地进行切片，它对于经典浏览器是不可见的，并纠正了 iPad 上的问题。
