在 iPhone 和 iPad 上查看时,我的网站无法正确显示。该网站(甚至还没有接近完成)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,该网站都能正确显示,但是,在 iPhone/iPad 上,“内容”div 与页眉和页脚之间存在微小间隙/空间。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稍微“缩小”,因此它不会与屏幕右侧的页眉和页脚对齐。如果我放大,一切都完美排列。这是从 iPhone 上截取的屏幕截图...
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)

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 会这样渲染页面吗?
在 iPad 上,当以低于 100% 的比例查看网站时,有时会出现一些伪影。其中一个特别明显:div 之间有 1 像素的线,就像在您的网站上的菜单下一样。
我找到的解决方案是在div之间添加“margin:-1px”。 Div 背景重叠 1 像素,如果进行相应的切片,则对于经典浏览器来说是不可见的,并纠正了 iPad 上的问题。
用途:
meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"
当网站显示在平板电脑或其他设备上时。这应该消除您看到的像素差异。如今,网站的设计应在语义上可扩展,以实现最大程度的跨设备访问。
对于我来说,如果绝对需要解决问题,我通常会构建一个 php 设备检测器。
.expand {
transform-origin: 0 100%;
transform: scaleY(1.01);
}
<div class="expand">Content for div1</div>
<div class="expand">Content for div2</div>
<div class="expand">Content for div3</div>
此 CSS 代码使每个 div 垂直拉伸 1%,与相邻的 div 重叠,从而有可能消除您所看到的可见伪影。
变换原点:0 100%;声明将变换的原点更改为元素的左下角(0% X 轴,100% Y 轴)。因此,当应用scaleY转换时,您的元素从底部扩展,有效地重叠下面的div。
在我看来,这是一种更实用、更安全的处理问题的方法,然后使用负边距,除非您每次在下一节中增加这些边距,否则我不知道它会如何工作。
